The assumption, here at least, was DB was aware other schools were or would be coming after JM. Even if that weren't true it's been said before that any AD worth his salt always keeps a "potential candidate list" for the most critical coaching positions. Plus, DB has lots of contacts and we now seem to have influential friends (Nick Saban) who would be potential contacts for advice on an important hiring like a football coach.
That said, this is taking too long when you see how quickly some schools fill openings and makes me wonder if JM really left UConn in a better situation than he found it.
There could well be lingering doubts about, again, whether UConn has what it takes to keep its football program viable and continue to grow its strength and sustainability. Someone equal to JM in status may not want to risk leaving a solid position and someone with less experience who's making a name for himself may have doubts about taking a job that's been so risky for so long.
Let's hope DB can find that aggressive, competent, coach with experience running a program who has the confidence to take the job.
