Fortunately, random Internet guys have access to something called the combine. He ran twice and his best official time was 4.7. I watched him multiple times throughout his Michigan career, and 4.6-4.7 is about what I would expect.
Regardless, as big as he is, there is huge difference between a guy his size running a 4.47 (on a pro day lol) and a guy, say like Ginn's size, that runs a 4.3, is quick, and can consistently catch the ball.
You and Growl get to share the award for most annoying person on the internet today. It's uncanny how much you complain. It never ever stops. you have a gift that nobody but you seems to value.
