No way. 48 hours of good weather and they will be in better shape than you think.
There were parts of the grass lots they didn't park for the Akron game that if you walked across you'd sink in a couple inches because it was still pretty saturated so imagine how bad those spots are now after all this rain. There was more dry weather prior to the Akron game too.
Let's not forget that there is a chance of rain again on game day that will factor into this, they aren't going to park cars in already sketchy lots then risk having more rain on game day making them even worse. I hate to say it but I'll be surprised if any of the grass lots are open Saturday. We've just had too much rain and even if it does stop for a couple days it's not going to be warm and sunny to dry them out in just 2 days.
