Talented as Gregory is, he's a high-strung guy, too. He definitely got into it in the Nebraska/Miami game last year, and could have been ejected. He talked a lot of trash, but he's with gone this year and I don't think any other guys for NU are known as trash-talkers.
Gregory left Nebraska as a Junior, and while we would have loved to have him this year, he's too good to have stayed. If it wasn't for the pot problem, he'd have been a top ten pick.
