"I watch a lot of Simeon," Gregory told NFL Media's Tiffany Blackmon from the Rookie Symposium on Thursday. "His length is probably the biggest thing I've taken notice of. He uses it very well and that's something I've really been trying to do. My long arm I think is getting better in camp and it's only going to get better the more I play, and Jason Taylor, he's real athletic, tall guy, long, kind of myself. So they're real athletic. They do a lot of good things and I'm gonna take the things that Coach Marinelli preaches and get off the ball. I'm trying to get off the ball as much as I can."
