I have plenty of first hand experience with the Jayhawks on this, and Kirk had much the same injury as Coverdale. They will put him on electrical stimulus 24/7 and the ankle will be tender but he will play. Hinrich had 20 points in 12 minutes on bum wheels.
The Indiana players have long arms and are able to clean the glass. That is where the game will be won. This IU team runs their offense very well, good movement, lots of screens. If it stays close(IU can clean their defensive boards), IU can pull it off.
I hope OU is underestimating IU like Duke did.
