Bobby Knight and I go way back — I was at Indiana University from 1973-79, including the great undefeated 1975-6 team featuring Scott May and Quinn Buckner. Over the years I've had the chance to notice that when he's coaching he's not particularly stable.
However, over the last year Knight and Brent Musburger telecast Big XII basketball games, mostly those involving KU and/or K-State. I've also heard him on the Mike & Mike radio show on my drive to work.
When he's not coaching, Bobby Knight is smart, witty, thoughtful, and doesn't just talk to fill the air. It's amazing.
Of course, I have no way of knowing what he's like off-camera, but it's a considerable improvement over the old Knight.
Maybe he should have started out as an announcer.
