Bucky is off his rocker. Good player, not nearly as good as Lacy. He's not as fast, he's not as agile, and he's not as tough. They both have size and decent hands.
Bell has a ton of wear and tear. He's coming off a 400 touch season. That's crazy. Kevin Smith of Central Florida came off a similar type college campaign and broke down in a year.
I think he's a solid RB, but he doesn't overly excite me. And there is risk with his usage. I see less Steven Jackson and more Ron Dayne.
