Every now and again it’s cool to use Twitter for a little heat check — toss a radical opinion out there and see how many people respond, and how they respond. After Kentucky beat North Carolina last Saturday, it was hard to resist firing off this Tweet: “This is the best team John Calipari has ever coached, and Anthony Davis is the best player he’s ever coached.” Man, Derrick Rose sure has a lot of fans out there. And it’s amazing how many people remember that Calipari coached the New York Nets.
