No matter how good a coach Fleck is - or becomes.......no matter how charismatic he is.........We are still talking about Gopher Football here.
The hard-core fan base for Gopher Football - at this point in time - cannot fill a 50,000 seat stadium. That is the cold, hard truth.
To get a sellout, the Gophers need one of these other factors: a marquee, big-name opponent........a big rivalry game where opposing fans will buy up any available tickets.......or really cheap ticket prices.
Now - at some point in the future - if Fleck is as successful as some people believe - then maybe the Gophers can sell out TCF on a regular basis. Maybe they can even generate enough ticket demand to think about expanding the stadium. But that is going to be a long process. Years long. Expecting fans to instantly flock to the team just because of the "Fleck Factor" is just expecting too much, too soon.
The Twin Cities sports market has been hearing and reading "The Gophers Suck" for almost 50 years. that is a lot of conditioning to overcome.
If the optics of a less-than-full stadium bother you, then maybe several thousand fans should bring cardboard cutouts with them, and prop them up in the empty seats.
