... systems. As GCHokie34 has pointed out before, Buzz' philosophy is to recruit the best players you can get and then mold your system to fit their abilities. Mike, in contrast, has a specific system that he runs and he recruits players with specific skill sets to fit that system.

My guess is that guys like Chico and PJ simply didn't fit in that well with what Mike is trying to do or they simply figured that they could get more PT elsewhere.

This kind of turnover isn't uncommon when there's a coaching change. Remember all the guys from James Johnson's team who ended up leaving when Buzz was hired?
