It was easy for Corey to excel in his first year because he was basically the only guy who could put the ball in the basket, and we had so many injuries that he basically carried the team. He was by far the best player on a terrible, injury-riddled team, and it's easy to look good under those circumstances.
It's a lot harder for him to excel within a system that wasn't just Corey driving the lane. Yes, he struggled much of the year, but sometimes to coach a player to get better, you have to strip him down and start from scratch. I kind of feel like that's what was going on last year, with a *real* coaching staff trying to shed Corey of bad habits and getting him to become a real PG instead of just the guy who will carry the team.
I hope and expect that, in the second year of Pike's staff, Corey will get back to being a difference maker in all facets of the game.
