Most of us watching last year's team are familiar with the bi-polar "Good Korie/Bad Korie" games. Korie was the starter, but there were games where he was a bad pass, missed shot, turnover machine. Bubu is an effective pg, if not top tier. He was was better on defense than Korie was, and like McGee (but to a lesser extent) he was an energy spark for the team. As mentioned, he did a much better job at the B12 tourney than Korie, a fact that Korie himself pointed out.
I don't know how much Bubu's game has/has not improved, but I seriously doubt he would start in the near future. It would not surprise me if he worked his way back into the high rotation, though. Bubu was largely passed over by college scouts as he played in the shadow of Doug & Harrison. Yes, he came to ISU as a walk-on...but he worked his butt off and was rewarded with a scholarship, which was renewed. I have no doubt that, once back in practice mode, he will put in the necessary effort to get himself back to what he was (or should have been) last November when our season started.
