As much as I hate to admit it, there seems to be something about Groce that just can't keep them down on the farm so to speak.
I agree, but my guess is it is more of the players not being able to handle Groce than it is Groce not being able to handle the players. In other words, Groce does not accept limited effort and committment.
I think that excuse works in moderation and it happens to lots of intense coaches like Groce. However, at some point, it also falls back on him for bringing in players who aren't prepared to handle his style of coaching. Too many guys have left early under Groce for my taste. You're never going to have 100% retention but I'd like to see it improve.
