I'd wager that it does for basketball, but not even close for football. But D1 football is new to UConn. Give it time, and they can deliver. Lots of people who are UConn alums don't care about UConn football, because when by the time they graduated (pre-2002), it wasn't really a big deal. That has changed. Newer alums care a lot more. That base will continue to grow.
But outside of alums, the state has rallied behind UConn basketball (mens and womens) and will do so with football as well, if they're in a real conference.
