07:15 AM ET 05.20 | For the better part of two months, change has been the operative word at Arizona. [The Wildcats] have made 10 player personnel moves, lost an associate head coach and hired a former star as an assistant head coach. Oh yeah, there was that Pac-12 officials controversy, too. ... [On Friday, Sean Miller] talked a lot about roster management, saying the Wildcats won't necessarily fill all 13 scholarship spots available next season. UA's talent began spilling over this spring in the form of departures by Grant Jerrett (pro basketball) and Angelo Chol (San Diego State). "Just because you have the number 13, I don't know if that's as important as it once was," Miller said.
