Coming from a drier place like Ft Worth, I wonder how the TCU players will handle all that humidity. I imagine their trainers will be all over the team with fluids in various forms. They haven't played any where with the potential for this type of weather since September 2009 when they visited Virginia and Clemson.
We get plenty of humidity in Texas with very high temps. Lots of our players played high school football in south and east Texas where the humidity is higher than it is in Fort Worth/north Texas. The weather will be an absolute non-factor in this game.
The crowd and hostile environment will be a factor. Frogs didn't look so hot on the road last year (gave up 61 points at Baylor, eeked out a game-winning FG at West Virginia, and nearly lost at Kansas of all place. Other than in the State of Texas, the Frogs only struggled on the road. By comparison, though, the Frogs played better on the road in 2012 and 2013 than they did at home. So who knows what kind of year it will be.
