Wilson said that Manziel has a very well-rounded game for a college quarterback and in particular was impressed with the speed of the 21-year-old's arm.
"He played under centre on all the throws," Wilson told the Cowboys' official website. "He showed movement throws, he showed drop-back throws, quicks, and he threw the ball all over the field.
"So I was very impressed. He was very accurate and had plenty of velocity on the throws, as well. I saw him at the Combine, where he didn't throw, so this is my first time to really see him throw in person - just wanted to see his arm strength. He has plenty of arm strength to play, no question about that."
Manziel's college team was the Texas A&M Aggies.
