A little background: I worked in venue management/ticketing for 14 years for two different countries in the industry. I worked outside of college football, more so with pro baseball (MLB owned my first employer) but I did work a game at Tulane and we did Tennessee and Minnesota.
As a spectator, the Rent is not a bad medium to small sized venue. I did not read about the renovations that are necessary and I'm sure everyone on here has seen my comments from my "tailgating podcast" hat (I hosted one of those one after I stopped working in that industry)... there's something to be said for how easy and affordable it is to park and attend UConn games. The problem is obviously going in and out of a power conference and having a losing record for a decade's worth of seasons. As
@kemba commented above, the open concourse is a great feature of the stadium. I've spent full quarters watching the game up there... also the food and beer (availability of alcohol) is something that should not be taken for granted. Some of these legendary stadiums have their issues. As I've said here before, my father is a Varsity O member (former Ohio State athlete) and my mom went there as well, and grandfather taught there. We've gotten tickets through the school connections and had seats where you had to sit behind a pole. If anyone went to Michigan this year, you'll note that the stadium is basically built on one-tier so if you are at the top you are going go be walking up 100s of stairs or waiting forever for an escalator that doesn't always work or elevator to get to the a high up seat and some of the sights lines where I worked for Tennessee are horrible. Minnesota built a new stadium and it's nice... but they have big 10 money...
Whether or not the stadium should be on campus is a whole other debate (certainly played out on here and on twitter) but for the time being, this stadium is fine. Check out where we are playing most of our games second half (and I'm a fan of UMass's on campus stadium and its situation.. you can actually ride a bicycle to the stadium from 5 or 6 surrounding towns which is pretty cool)... but we definitely have a very good stadium at this time for what we are.
No one is not going to UConn games because of the state of the Rent.. they are not going because they have made 1 bowl game in the past decade, the stadium isn't on campus or because they aren't in a conference / schedule. Benedict/Mora are working on these issues (stadium location - they are making it easier/better for students)... I'm in a holding pattern here for a few years. If UConn is the BYU of the East in a few years, there's gonna be some decisions that need to be made.
