Best manager? Sure, that's an overstatement. But best manager for the Red Sox, I don't think that's an overstatement at all. His familiarity with the Sox organization is very valuable, especially his familiarity with the pitchers, which is really where their struggles all boil down.
Also, Farrell publicly denied any merit to the Vizquel comments this year on WEEI today.
If you ask me, I think he's the perfect guy for the job right now. He's got the strong demeanor to him, gets along well with the leaders of the team, can straighten out Buch, Lester, and potentially even Lackey (who had a 4.40 ERA and 215 IP in 2010, something I think we would all kill for from our #5 man next year).
The fact that guys like Lester, Pedroia, and Ortiz all came out publicly and expressed how excited they are for this hiring just shows how much this hiring differs from the Valentine hiring.
Look - Was he manager of the year in Toronto? No. He made some mistakes. Had some hiccups. Fine. But you have to look at this from the standpoint that he knows the Red Sox organization, the core players in the Sox, and he knows how to operate this team. He also knows you can't rely on the 3 run HR and expect to go far (See: 2012 Yankees ALCS).
I, personally, am very confident that he and Cherrington can turn this team back into an annual contender as early as next season, but at least by 2014.
