His age isn't a problem, he's a good coach. Even if UConn was in a position politically to make the massive kind of offer it would take to land him, they aren't in a financial situation to outbid a P5 that really wants him.
So yeah make the call, but unless he really has a desire to come back to a stop he spent 3 years a decade ago at and was demoted from OC (the only year since 2006 where he wasn't an OC or Head Coach); you work on plan 1A at the same time. Ultimately there will almost certainly be P4 schools with far greater resources that will come calling and while UConn may make an offer that sets the price to beat, they'll have the resources to beat it.
