If you remember the start of the dramatic season, Philadelphia had a minor scandal after telling Nick Castellanos not to report to spring training.
Castellanos was growing into an embarrassment, having not only admitted to bringing beer into the dugout during the game, but openly questioning his managers and coaches because "they hadn't played the game" or "they haven't paid their dues" or the like.
I largely consider this to be jock posturing, and there are certainly plenty of managers who have had long and more or less successful managerial careers despite no MLB playing experience (Manny Acta, Dave Bristol, Terry Collins) or scant MLB experience (Tommy Fucking Lasorda).
But the two jocks in the booth (Darling and Hernandez) and the guy who likes to be liked by the jocks (Cohen) were giving some credence to (if not outright endorsing) the notion today, claiming that there are techniques for managing your body over the course of a season, and plays that you don't pick up — and presumably cannot therefore teach — except through the repetition of a 162 games at the top level.
This was mostly directed at Tim Leiper — who in fairness, has had a pretty unimpressive (to the extent that a third base coach can impress) — debut season with the Mets, and to a lesser extent Carlos Mendoza (who they couldn't praise enough two weeks ago), as well as the other non-MLB-experienced coaches on the staff. Leiper had just failed to coach AJ Ewing into breaking for the plate when an infielder tried to freeze him up and then go for the double-play.
I still think it's jock posturing. On the other hand, taking the small data set of the team at hand into account, it's not like this team has looked well coached.
