Mullen noted the move also brings about a different mindset.
“I think so,” said Mullen. “Training camp is different and it has to be different. When you go out there it allows you to have a whole different mindset.
Like spring ball is different and it’s open and we have fans there and crowds there. There is a lot of teaching and new things going on that you haven’t done before (in the spring).
“Training camp is a time to get locked away and just only football. There’s no school going on, no girls on campus and there’s nothing. It’s just all ball and that to me is part of it that this is a different deal.”
Mullen said the team worked Sunday on all aspects of the game and the coaches were still in a “teaching” mode at this point of camp.
MSU will don full pads today for the initial time in fall camp and will then begin two-a-days on Tuesday.
