Most managers stay in their office and keep the f*** out of the clubhouse and let boys be boys.
Terry Francona, for example, wasn't even aware that all his players were taking shots of Jack Daniels in the clubhouse before every playoff game during their first championship run. And when he happened to pass thru the clubhouse before the clinching world series game and saw the boys taking their shots, he was surprised to see it yet downed one too (when offered one.)
Francona also had no problem with Beckett, Lackey & Lester (and any of his starters) drinking beers in the clubhouse on games that they weren't pitching and also thought it was no big deal when his players wanted Popeyes chicken delivered to the clubhouse.
Managers aren't babysitters and Francona is viewed as a pretty good manager, no?
