There have been plenty of changes around the Notre Dame football program.

Coach Brian Kelly nearly completely turned over the coaching staff, retaining only Tony Alford from former coach Charlie Weis' staff. Alford was put into a new role, moving from running backs coach to receivers coach.

And the changes have gone over well, according to some of the former players.

"They seem excited," said former Irish center Eric Olsen, who worked out during Notre Dame's Pro Day Tuesday. "Anytime there is a whole coaching-staff change, strength coach and everything, it's got to be tough because you don't know what you are going to get."

With the new weight training staff came a new training regimen, under the direction of strength and conditioning coach Paul Longo.

Notre Dame also introduced a training table to help players with their nutritional needs throughout the season.

"I was like, of course, a month after I graduate," former offensive lineman Sam Young said of the training table. "Everybody has said they are busting their ass and enjoying it. It's kind of one of those things where guys are buying in and at this stage it is phenomenal.

"I heard a lot about what Coach Longo is doing in the weight room. They are embracing it. They are coming up (to me) and saying, 'This is how much body fat I lost.' Guys are losing 3, 5 percent body fat in a couple of months, getting stronger, getting bigger, getting faster. You just look at it and say, 'OK, things are going in the right direction.' "

But the biggest change has come from the non-football workouts called "Camp Kelly."

Kelly gets his team up early in the morning to run drills that help build unity and leadership.

"They got murdered a couple of times already," Olsen said of what he has heard of "Camp Kelly." "A couple guys spend the morning standing over a trash can already."
