He's already got a nationally known nickname, "Coach Cal." Coach Cal has the makeup to handle all that goes with being coach at Kentucky, which is the No. 1 college basketball job in the country. He'll get the best players in the country to attend Kentucky. Look what he did at Memphis, which is in the same state as SEC power Tennessee.
Memphis, where he coaches now, is not likely to get out of C-USA and into a big conference anytime soon. There just aren't any holes for new members.
If he's offered the Kentucky job, he takes it.
