"So far, so good," Pettinato said. "This is always the time to work on fundamentals and stuff. It is going good so far, coming back off the knee injury, I feel good.
"When you are healthy, it just reminds me of how fun the game is and how much I love it. When I was hurt, it is a struggle."
Although Pettinato is completely healthy, he admits he lost something due to his injury.
"The quickness in my feet," he said. "Coming off the ACL injury I was a little rusty and slowed down a lot. Out here I will work all summer. I already feel quicker on my feet and can keep getting better."
With only five more practices to go, Pettinato knows exactly what he wants to prove to the coaching staff.
"I think the biggest thing is that we have five more practices to work before positions start getting set in stone coming out of camp," Pettinato said.
"Out here, I think we are all trying to show everything we have so the coaches can evaluate us and see who are going to be the top three guys come fall."
Not only is the competition on the defensive line an open one, but it also adds depth.
"Every position is wide open," Pettinato said. "On the defensive line we have a bunch of good players like Reggie Gilbert and a bunch of young guys that are coming up that can participate this season.
"It's nice. We could have better rotations and guys get to go out there with fresh legs, so it is important for us."
