It's a long-held belief that Kentucky coach John Calipari and Louisville Cardinals coach Rick Pitino hate one another. I've never really believed that; I've always thought the subtle jabs, if that's what they were, were for show.

Maybe there was a time when they were younger when that might have been true. But now? I don't buy it.

Sure, it's a fun facet of the Kentucky/Louisville rivalry to believe that the coaches can't stand one another. But they've said over and over again that none of that is true. And STILL nobody believed them.

So I was amused by CBS Sports national columnist Gregg Doyel's most recent blog. He's written about this coaching rivalry before and has always enjoyed it. But even HE is having his doubts now.

Read his column here and see if you agree.
