MM said they practice with the heat off and the doors open. It is cold but not physically punishing cold.

They also got a couple practices outside before the snow. They don't want anybody slipping and blowing out a knee in the snow.

Of course they don't want anyone to slip in the snow. That is why, in the past, they cleared the practice field after a snow fall.

"We have the ability to practice outside, as we did not in '07, just because of the field conditions," McCarthy said. "Having Nitschke Field now that's heated is a big bonus for us, so the ability to handle the football is something we've been trying to spend a lot of time on the last month, and having the opportunity to do it this upcoming week and next week is really beneficial."
