Duke vs. North Carolina. Kentucky vs. Louisville. Connecticut vs. Syracuse.
Some of the greatest rivalries in sports play out on the college basketball court, but this season marks a changing of the guard in many of those rivalries as conference realignment has done away with annual matchups like UConn vs. Syracuse while carving out the potential for new ones.
Rivalries also exist in recruiting, and while they’re often an extension of natural rivalries on the court, that isn’t always the case.
Jim Calhoun and John Calipari had a huge recruiting rivalry when they were the head coaches at UConn and UMass, respectively -- despite the fact their teams never played -- stemming from the recruitment of Marcus Camby.
So whether it’s an extension of a conference rivalry, a personality clash between high-profile coaches or even the consequence of a particularly contentious recruitment process, recruiting rivalries can take shape in a number of ways.
