Maybe Willis is just tired of every time he makes any little mistake he gets pulled and yelled at by Cal while "others" on this team that make mistake after mistake and never get pulled because they have 5* by their names.
Sorry, but the facts are one kid has been here 4 years, been prodded, and begged to compete--and the others are or have been here less then 10 months. Out of the 5 Stars you are criticizing--I'll go down the list for you:
Fox--your most important player. How does team look when he's out of game? Or misses games?
Monk--Most explosive offensive player and guy who has to be on court for court spacing to be remotely respectable. Take him out and this team struggles to score.
Bam--He's been playing out of position due to fact the other parts of this team are lacking and unreliable. He's a PF masquerading as a Center. He plays hard every game. Does he play smart? No--he is a FR.
Briscoe--In most classes he's not a 5 star. However, I think he plays hard, and if anything he's trying too hard to be something he's not and has people in his ear that don't help his case. Last night's version was the version that fits this year's team perfectly and when he's at his best.
Gabriel--His strengths in HS were playing near rim and rebounding and shot blocking. He's expanded to be a good outside shooter--and lacks ball handling skills (common theme lately with Young, Poythress and lack of SF). So he's learning on job--I would still go with him and think this team wins with him playing more then Willis. He is going to compete/give effort and you don't have to wonder if he'll show up.
So let's focus on the instate kid. Maybe there's a reason Willis originally committed to Purdue. He wanted the big stage, and UK has delivered. He didn't see court his first two years--and team went to back to back Final Fours, NC game appearance. His role increases, he's an upperclassman that younger players rely on as he's actually played significant minutes--yet he's a guy who doesn't bring intensity or focus and is a defensive liability. So what part of team is crappy? Defense? Yes. Intensity? I'd say they drift. Sounds like your Sr you want to play more. When new people come into a program, they look at how players who have been around approach things. Willis is about as awful of an example as you could set. He disappears, plays scared, doesn't compete when it's hard, checks out, and then is a front runner--when all is going well he'll be rolling. He's a SR who has to be begged to do his role and compete. Sorry--but if anything--this is a signal to Cal that he should avoid more "instate favorites" and go national and stick to the talent he believes in--which was producing the results you all covet.
