Weber has been slighting Self for almost a decade now. Aside from the funeral he boasted he "kicked [Self's] butt" when he coached SIU against Illinois when Bill was there. (Even though he lost the game.) Then just in the last week or so he made a crack about KU getting the title because of the officials. Which while true is a really dumb thing to say, especially when the season's not over.
But if that wasn't enough, think about what Self went through losing to Bucknell with Roy's players while oscar Weber got coach of the year with his ... and acted like he did it all himself too.
There is a story on the Illinois board about a couple fans that bumped into Self at the Final Four in New Orleans right after Weber was hired. They wanted to know if we hired a good coach and he wouldn't answer, he just looked at Norm Roberts and smiled.
Look, it's true KU has better players and better coaches ... but Bill's teams come out flat at times, and that is never gonna happen against KSU so long as Weber is still there.
