Sports Illustrated's Grant Wahl -- one of the better college hoops writers working, which you probably already know -- has a pretty interesting breakdown of John Calipari's entree into Kentucky basketball this season. You should totally read it. It covers all the usual bases (Calipari's popularity, his recruiting class, his troubled exit from Memphis). But it focuses most of its time on the relationship between Calipari and Louisville coach Rick Pitino.

You may have known these two supposedly hate each other, but did you know ...

• That Rick Pitino initially recommended John Calipari for the UMass job and paid $5,000 out of his own pocket to make sure the Minutemen athletic director at the time sealed the deal?
• That John Calipari first met Rick Pitino as a teenage camper at Five-Star camp in Pittsburgh?
• That before he took the Kentucky job, Calipari called Pitino and asked the coach what he thought? And that Pitino told him to take it?
• That Kentucky fans are sort of crazy?

OK, so you knew that last one all too well. But the other three speak to a more complex relationship between the two coaches than what you've heard. For his part, Calipari insists he's on friendly terms with Pitino, and clearly the two do share some sort of bond. But whatever similarities bring them together -- the Armani suits, the slicked-back hair, the stints in the NBA -- they also clearly brush up against one another the wrong way.

Fortunately, we millenials have devised a word for this: frenemy. That's totes (totally, natch [naturally, duh]) what Calipari and Pitino are. They like each other and they wear the same clothes, but they'd also like to punch each other in the face on occasion. Frenemies forever, y'all!
