"There was a lot of anticipation getting on the and field seeing how practice was going to be," he said. "After it happened, I feel comfortable and it should be good the rest of the week."
Trattou looked good on the practice field at Gustafson Stadium. He stood out quickly, showing a great first step and the ability to beat whoever was in front of him on his way to the quarterback.
"I did pretty well today," Trattou said. "I had a couple sacks. I was winning the majority of the battles.
"I was just using my quickness, because these guys are a lot bigger than me. I was basically running right around them getting the job done, so it's all good."
Trattou came to San Antonio with an agenda.
"I'm just going to work to earn a starting job, that's my goal. I'll just wait and see where I am on Saturday."
Where Trattou will be when he arrives at Notre Dame is in the mix for playing time. The Irish graduate starting ends Victor Abiamiri and Chris Frome, opening the door wide open for young guys to start and or earn reps.
Playing against the caliber of competition Trattou will see this week is a huge help in getting him ready to compete at Notre Dame.
"It's really good playing against these top guys, it shows you really where you're at in the country," he said.
After one day of practice, Trattou knows the answer to that question as well.
