"I've been kind of partially amazed that he could do what he's done," Kelly said recently, per Phillymag.com. "... There was one day here, you can check with him, I think he went from here to an Army training session and went out and had a couple PT tests that he had to pass and actually one of them was a five-mile test. He nailed it and came back and didn't miss a day.
"He's been just a guy that you see every day just getting a little bit better, getting a little bit better. As I said the other day, a real intriguing prospect but just amazed at everything that Alejandro does to be honest with you."
Villanueva's size and versatility -- he played offensive guard and tight end at Army -- offer compelling options for the outside-the-box thinking Kelly.
"For me, it's all uphill and that's the way I have to look -- is just up," Villanueva said last week. "So hopefully this work that I've put in during this offseason will pay dividends in training camp."
