Sorry, I just now saw this post.
As people might know, I've probably been outspoken about UConn as a possible candidate in Big Ten expansion longer than anyone. I don't have any new insight as to the status, but as of a year ago, the Big Ten was keeping an eye on the progress being made in upgrading the research arm. UConn has forged some excellent friendships in academic circles with Virginia, Illinois and Ohio State as well as Michigan. Virginia is key because there are a lot of folks in B1G circles that envision that pair as being 15 & 16 when the Maryland stuff settles. Oh, sure, Virginia will continue to say publicly it's committed to the ACC and in an ideal world, that's true... but it's going to listen when the time is right.
If Ohio State and Michigan both get on board for someone, it carries a lot of clout in the league. I think UConn is a real possibility in the next few years. Right now, the league is just taking its time and making sure Rutgers and Maryland are settled and it wants to see what happens with the exit fee. The Grant of Rights, I maintain, is not the deterrent people think, though the league is probably focused on eastern expansion for now.
