Without question, the mental part of the game is the biggest deficiency right now. You are correct on that point.
Speaking of great mentality and approach to the game, let me say that I watched the Nebraska vs. Texas women's volleyball match over the weekend. Coach Cook and the team went into the lion's den in Austin and really demonstrated grit and resilience. Watching how Coach Cook controlled the action not only through timeouts, but also through challenges was a great example of the mental part of the game on display. Each time Texas was prepared to go on a run, Coach stepped in to slow the tidal wave and get his team re-trenched. Congrats to the ladies on a Final Four appearance!
Let's just face it, we do not have that level of coaching talent in the football program right now...
