He makes Darren Sproles look huge.
At only 160, you can't get clobbered by 250 pound LB's and expect to hold up. I could see him returning kicks and maybe running out of some wildcat formations, but that's about it.
He won't get a sniff from a team before the third day. I wouldn't say he has character issues, but he's made some bad choices in his personal life. To his credit, his upbringing was as rough as it gets with his parents dying of AIDS before he was even in high school and watching his best friend get shot.
