Murray, the dynamic and diminutive Oklahoma quarterback, could go as high as the No. 1-overall pick in the National Football League draft, as the Cardinals are interested and might part ways with Josh Rosen - their first-round pick a year ago - to make way for Murray.
The Sooners clearly set Murray up for success, holding the throwing session indoors and keeping Murray stationary in the pocket, but he made the most of his audition.
That makes it easy to wonder if Murray knows something that the rest of us don't.
"I felt fantastic leaving the combine", he said.
Zorn, the one-time head coach of the Washington Redskins, has spent much of the last month working with Murray to prepare him for this moment.
"You get a perception in your mind about what somebody's going to be like, but when you see it in person it was a very, very strong performance", Oklahoma coach Lincoln Riley said. "I thought every meeting I had went well".
In his first interview since those remarks, Murray declined to address Casserly's comments directly, before saying, "I don't think I would've done what I did [last season] if I didn't understand what defense were doing". "At least to my face, no one was negative. I had a great experience". "I think the film kind of speaks for itself".
If they opted to do so, the Giants could package those picks to move up in the first round, but they are not expected to be heavy suitors for Murray, based on his size (he is a shade over 5-foot-10). Murray declined to be measured again Wednesday, but weighed in at 205 pounds. Murray is hoping he just did the same.
