The beer and chicken thing was useful for the media to highlight because it was a reflection of the lax attitude on the Red Sox which contributed to their collapse. Symptoms of their conditioning problems appeared the previous year as well, with a spate of injuries--and some made note of that.
In my view, the real culprits were the management, who ran too loose a ship. The media points fingers at the players, but the management set the tone. Certainly Tito, probably Epstein, and maybe also LL and Henry. Beckett, for example, is a current media target. He may have enjoyed a beer in the clubhouse on off-days, like many other players do, but he had a very good year, and was one of those who started the season as though he was in shape. I give him credit for that, and wish him well this year. Wouldn't mind having a beer with him sometime.
