Why don't they just move it?

We all knew a football game in Wrigley was a bad idea, but this seems like way too much trouble. Seriously, they're just now getting aorund to dealing with this? The dimensions of a football field haven't changed since they decided to try this. They should have know when they announced the idea last year it wouldn't work. I think marking off yardage every change of possession is too tiresome an investment, bench placement's now too unfair an advantage, and the whole scene to inhospitable to the game to try this again next season without changing the physical structure.
