Brandt said Gregory is a great talent, but he always would advise an underclassman to stay in school to mature physically and mentally.
"Ideally he should be 275 pounds," Brandt said. "Practice hasn't even started yet. Historically once practices start — and even though they're eating better than before — they usually drop 10 pounds. His whole thing is, right now, he's a very good undersized defensive lineman."
Nebraska coach Bo Pelini said Gregory has benefited greatly from spending the summer in Lincoln and training with teammates and the Huskers' strength and conditioning staff.
"He's only scratched the surface of what he's going to be down the line," Pelini said.
Pelini is one of the people who have cautioned Gregory about getting caught up in statistics.
"It's about developing yourself, playing fundamentally sound, doing the things that you need to be successful on an every-down basis," he said. "I think he understands that. He's more physically developed than he was when we first got him. And he's continuing to grow, get bigger, and put some more meat on his frame. And as that happens, I think you're going to see a guy who becomes an even more well-balanced player."
