Been wondering about that myself. I chalk it up to system. BellyCheck's system seems to be geared to plugging in new parts (he's usually quite active in FA market) AND to adjusting on the fly (he's not so locked into a certain way of doing things). Stubby's system and to a large extent Dom's system seems extremely complex, meaning it takes quite a bit of time to get new guys up to speed, AND Stubby seems locked into his system to the extent change seems difficult.
But then I'm on the outside looking in. I really am pretty much mystified as well.
