Yet, point guard Sam Grooms won't allow fatigue to stand as a reason for OU's second-half struggles.
"That's an excuse," Grooms said. "Everybody wants to make it [an excuse] for us; I'm not going to accept it. It's not."
Even if it is not an excuse, it is a factor. But, as Grooms says, it should not be a defining factor.
"When you're out on the court, even if you're a little bit tired, you want to win, so that should take over and knock the fatigue out of the way," he said. "You should be able to play through it, get extra possessions and actually come out and do something. Fatigue is not the (reason) and I don't think that's where we should go with that."
