Whaler's comment was that virtually none of the revenue from the stadium (concessions, parking, etc) are UConn's. Having a stadium that UConn claims as its own rather than rents out would redirect that revenue to the athletic dept.
Beyond that, I admittedly have a bone to pick against the Hartford stadium to begin with. What happened there is nothing short of criminal. The original drafted plan there was to have a functional supermarket and mixed income apartments there. The plan then included a stadium while keeping the originally planned supermarket and apartments as part of a deal. Then the stadium came and there were (and I don't anticipate there ever being) a supermarket or apartments. The whole thing was a schill. There's a man named Rex Fowler who put years of research and advocacy into this, and a long article was written about it (I think it was on CT News Junkie, but can't remember).
And to top it all off, the $60 million project (or did it end up being closer to $70?) sits just blocks away from Clark St. School, closed down because of PCBs with no replacement in sight, MLK School which may be shut down, and a proposed closing of Simpson Waverly School. These kids lives are basically being destroyed by austerity while our city bankrolls a minor league ball team to move 10 miles down the road so we can watch a couple of dancing goat mascots and drink 32 oz beers.
