I think some would contribute it to poor PG play. Lewis Jackson was a 2 time Cousy award candidate. Saying PG's can't play in Purdue's system is again, simply wrong. I know you don't like the system and that's fine, but you're wrong about PG's playing in the system. Ronnie was just a bad fit and Painter couldn't get him to do what needed to be done. Take a look at the Indy Star article posted on the first page.
Anyway, the background story is that Ronnie's dad, who was in jail during most or Ronnie and Terone's childhood appeared back on the scene and got into Ronnie's ear. He was never happy with Ronnie's decision to go to Purdue. Ronnie was happy last year, and played the exact same role this year, and all of the sudden, everything is terrible. He's not a bad player, but he didn't fit and if U.T. picks him up, I hope he fits in better. He isn't a bad kid.
I will agree that Purdue has had 2 terrible seasons back to back. 3 seasons ago they were a NCAA team, losing Kansas by 3 in the last minute of the game in the 3rd round.
