A few points:
1) I have season tix. I drive from Boston for RU games. Yankee Stadium saves me 90 or so minutes. I'm not excited for this game. If RU makes me pay for it as part of the package, I'll go, but it's not my first choice. It would actually be the first time I elected to go to a Rutgers game at Yankee Stadium.
2) There's a reason why the Raiders are literally the only football team left playing in a shared-baseball stadium. The sight lines suck. Bad. Show me where a good seat is in Yankee stadium for a football game.
3) I get Penn State fans feeling like they can fill Yankee Stadium. Beaver is 106k. Yankee Stadium is 52.6k for football (I think). Rutgers is 52.4. Penn State just needs to get half of it's season ticket holders to travel for this, not to mention area alumni who suddenly have a closer game to attend. Rutgers actually needs to sell more tickets! If Rutgers selling out a home game for Maryland is not a forgone conclusion, no way it will sell out Yankee Stadium.
4) The wrestling doubleheader is an obvious way to try to market the game further. I think the AD is trying to make the best out of what could be a poorly attended game.
5) If I were leaving from Rutgers stadium, I'd be planning for an 1:15-1:20 minute drive. Not terrible, but I wouldn't call crossing the GWB on a Saturday morning to go to a tailgate, that RU could've hosted in Piscataway, an appealing idea.
I do understand some of the "whats the big deal" arguments, I just dont really see any upside to playing in the Bronx of all places.
