Valentine developed a reputation for throwing his players under the bus, something that continued to stretch his relationship with the players thin until it seemed to snap once and for all.
The most notorious incident was when just a few weeks into the season, Valentine blasted veteran Kevin Youkilis during a TV interview in a statement that seemed to question the third baseman's commitment. He said:
I don't think he's as physically or emotionally into the game as he has been in the past for some reason.
It prompted Dustin Pedroia to fire back in defense of Youkilis and of course, led to another poorly-put retraction from Valentine. Youkilis was later traded, and this particular occurrence took a lot of the blame.
Then there was the time that youngster Will Middlebrooks entered the dugout after a couple of errors and Valentine reportedly remarked, "nice inning, kid."
Valentine claimed not to have meant any malice with it, but it certainly didn't please the players within earshot.
And then the incident that started it all and set the tone for the season: Players were allegedly very upset after witnessing Valentine publicly lay into former player Mike Aviles during a drill in Spring Training.
Even after being fired from the organization Valentine kept on talking, this time directing his negative comments at slugger David Ortiz, who spent the end of the season out with an Achilles injury.
But Valentine suggested instead that Ortiz quit on his team after the blockbuster deal in August:
He realized that this trade meant that we're not going to run this race and we're not even going to finish the race properly and he decided not to play anymore.
If Farrell wants to maintain a solid relationship with his players throughout the season, he'll keep his criticisms constructive and behind closed doors. On air, he'll show nothing but support.
Players are more likely to play for a manager they respect, so getting the approval of veteran players like Ortiz and Pedroia is key. Luckily, since Farrell already has experience working with both, he's off to a good start.
