Given his reputation throughout baseball as a straight-talking, old-school baseball guy, if Dallas Green was going to put his career in perspective with an autobiography, he had to go all-in.

Green doesn’t disappoint in The Mouth That Roared: My Six Outspoken Decades in Baseball written with Alan Maimon.

From his time as a journeyman pitcher who was constantly on the fringes of being sent to the minors, Green was a players’ player who worked as both a union representative in the nascent days of the MLB Players Union and saw the geographical shift from the owners controlling everything to the unfettered free agency that accompanied Marvin Miller, Curt Flood, Catfish Hunter and Andy Messersmith. His feelings on the matter have swung from decrying the players’ indentured servitude, clamoring for some say in their careers, battling for a crumb of the pie from ownership to today wondering how much good the $200 million contracts are doing for the game.

Green has the breadth of experience from functioning as a player clinging to his career with arm injuries and poor performance to a minor league director to a manager to a GM. He helped Paul Owens build the 1970s Phillies who almost but not quite made it over the hump from annual division winner to championship club, then went down on the field at the behest of Owens when the soft, inmates running the asylum approach of Danny Ozark was no longer working, got into the faces of veteran players, benching them, threatening them, ripping them publicly and dragged them to a World Series title in 1980—the first championship in Phillies’ history.

One interesting footnote from 1980 is that with all the complaining from closers of yesteryear about the one-inning save in today’s game, Green didn’t adhere to it during that championship season because nobody adhered to it until Tony LaRussa implemented it in 1988 with Dennis Eckersley. Pitchers like Tug McGraw, Bruce Sutter, Rollie Fingers and any closer worth anything pitched multiple innings. That had drawbacks that aren’t discussed by the “in my day” crowd (Green isn’t one of them) as McGraw pitched two innings in the first game of the World Series, had worked very hard including three innings pitched in game 3 of the NLCS and appearances in games 4 and 5, plus game 1 of the World Series, and wasn’t available to close in game 2 of the World Series with Ron Reed doing the job. That would never happen today.

The original intention was for Green to take over for Owens as Phillies GM with managing only a short-term gig. Owens had no plans to retire as the Cubs came after Green calling—repeatedly with consistently sweetened offers—to take over as their GM with carte blanche to run the team as he saw fit. He turned them down multiple times before finally saying, “Yes.”

With the Cubs, Green turned a perennial loser into a division champion with smart trades in getting Ryne Sandberg, Rick Sutcliffe and Ron Cey. However, as should be noted in today’s game where there’s the perception of the GM with absolute power, it doesn’t exist for anyone and never really did at any time. Even today’s luminaries like Theo Epstein and Billy Beane answer to someone. After his first season as the GM in 1982, Green thought he had a handshake deal in place that would land Dodgers free agent first baseman Steve Garvey for the Cubs. As a corollary to that trade, the Cubs would have traded Bill Buckner (a player Green didn’t want on his team because of selfishness and in whom he took a certain perverse amusement when the 1986 World Series was lost by the Red Sox in part because of Buckner’s error) to the Phillies. The Cubs upper management didn’t okay the deal and Garvey wound up signing with the Padres who, ironically, beat the Cubs in the 1984 NLCS with Garvey helping significantly. It was then that Green learned what he was dealing with working for a corporate ownership in the Tribune Company. It was Green’s constant pursuit of putting lights in Wrigley Field that played a major role in the stadium being saved by their installation in 1988.

After the Cubs won the division and appeared to be on their way up, it became a case of too much too soon. Green’s plan was to use his own long-term contract to rebuild the Cubs’ dilapidated farm system, sign key free agents, change the culture from one that accepted losing, and make wise trades to have a consistent pipeline of talent. When the Cubs won the division in 1984, it was expected that they were going to win a World Series shortly thereafter and when they took a step back in 1985 and came completely undone in 1986 and 1987, Green was fired. The signal that it wasn’t going to work as Green planned with the Cubs occurred when an executive with the Tribune named John Madigan began going to baseball meetings, learned and used the terminology and started interfering with baseball moves. From Green this was an example and a none-too-subtle shot at people who have no baseball experience thinking that learning a few catchwords is a substitute for knowing the game itself through experience.

Following his firing the Cubs won another division title in 1989 with a team comprised of players that Green had acquired and drafted. By then, he was managing the Yankees.

For all the enemies he hammers in the book like Bobby Valentine (“He thinks he knows more about the game than anyone else.”); Gene Mauch (“lack of people skills”; “inherent mistrust of younger players…”); Joe McIlvaine (“I ended up hearing through the grapevine that he might be spending a lot of time on non-baseball activities in Atlantic City.”); and Buckner (“Buck was happy to put his numbers up, but he was never truly content. And he most definitely never embraced the idea of baseball as a team sport.”), Green never took overt shots at George Steinbrenner from his brief tenure managing the Yankees.

No one who knew Dallas Green and George Steinbrenner could possibly have thought it was going to work not just because of the clash of personalities of one person who wanted things done his way and the other one who wasn’t going to take crap (you can pick which would be which), and it inevitably and quickly failed with Green fired in August. It didn’t help that the 1989 Yankees plainly and simply weren’t any good and wouldn’t be good again for another four years in large part because of Steinbrenner hiring people like Green and not letting them do what it was that got them hired and made them successful in other venues in the first place.

Green then joined the Mets as a scout and eventually took over as a “clean out the barn” manager. He couldn’t get through to many players from veteran Hall of Famers like Eddie Murray and young Jeromy Burnitz, but he did forge decent relationships with and got good performances from Bret Saberhagen after a rough start and John Franco. He stated openly that his experience in developing players with the Phillies told him that the Mets heavily promoted trio of “Generation K” Jason Isringhausen, Bill Pulsipher and Paul Wilson weren’t ready for the big leagues as the centerpieces when they were pushed as such. He’s right when he says all three needed more time in the minors to learn how to pitch.

An interesting aspect of Green’s career is the influence he’s had and how players who may have hated him while he was managing them took his lessons into their own management careers. Larry Bowa couldn’t stand Green and felt he was too openly critical of players. The relationship wasn’t bad enough to prevent Green from acquiring Bowa in the Sandberg trade to play shortstop for him with the Cubs and to trust him to mentor top draft pick Shawon Dunston. Nor did it stop Bowa from becoming a manager whose style was nearly identical to Green’s. As a player he didn’t like to be yelled at; as a manager, he learned that some players need to be yelled at. Like Green, he got fired for it.

Today as he’s an assistant in the Phillies front office, he sees the way deals are made with a nearly nonexistent focus on people and a detrimental focus on numbers with the money players are being paid and the almost misanthropic nature of the people making the decisions today in a cold, corporate atmosphere and yearns for a time when baseball people made baseball decisions when he says, “Many general managers today only know how to evaluate talent in front of a computer.”

The final chapter of the book is dedicated to his granddaughter, nine-year-old Christina Taylor-Green. Christina was one of the people killed in the Tucson, Arizona assassination attempt on Congresswoman Gabrielle Giffords. The old-school baseball man Green is also old-school when it comes to the right for responsible people to bear arms, but his case for gun control is coming from someone who doesn’t see any reason for automatic weapons designed for one purpose—to kill people—continue to be sold and has lost a loved one to make this point tragically clear.

While it would have been easy for the book to degenerate into a treatise on the superiority of the old school both on and off the field; for it to turn into a Richard Nixon-like unfettered attack against his lengthy enemies list, Green manages to state his case as he sees it with a matter-of-fact tone that has no hallmarks of a vengeful attack or manufactured controversy designed to create buzz and sell books.

A person whose life has been steeped in in-the-trenches baseball will see their beliefs validated, but those who are relatively new to the game and think they’re experts after learning how to calculate OPS+ will also find value if they read it rather than use it as an indictment of the old school and take what Green says to learn from his successes and acknowledged mistakes.
