What is Gaines reaction after the loss to Marshall?

He is frustrated and stressed out!

The loss also is an excuse for the grumbles about whether Gaines has the ability to coach a championship team to surface again. It is also a game where the alternation of great plays and sloppy mistakes only adds to Gaines’ frustration. However, for the players, it’s a whole different world: they find a party at the home of one the boys whose parents are out of town, and they put the loss behind them. After all, they are still the gladiators, envied by everyone, living in their own private kingdom.
