Timing is everything. ACC in the fall of 2011 were desperate for a "football school" because they were having a poor run of results and FSU and Clemson's SOS were being constantly criticized by the national media. Also, because UMD was leaving, the door was open for other schools to leave thus the more academically oriented schools needed to acquiesce to the wishes of the football schools. Right at that time UL was on the way up and UConn football was in freefall. Jurich sealed the deal, but it was a very uphill battle for UConn at that time.
Had UMD left 2 years earlier or later (now that FSU has won a NC and UConn basketball has proven there is life after JC) UConn would have gotten the invite.
