Mark Blaudschun of TMG Sports first reported that UConn will be paying a $17 million exit fee to leave the AAC, which was then confirmed by multiple reports, including the Hartford Courant, who added that UConn will be officially joining the Big East in July of 2020.
UConn made the news official with a press release later in the morning.
The exit fee will be paid in part by two lump sums which represent withheld payouts from the AAC contract, covering around $11 million. UConn will make annual payments over six years for the remaining $6 million, so ultimately it seems that this is the only money coming out of pocket.
