I think he's a lot faster than the huddle gives him credit for. He couldn't beat the angle on one punt return and now he's slow. The guy did run as high as 4.39 at the combine. Which combined with what we see he must accelerate very fast but doesn't have long speed. I think he's faster than any wr we have not named Gettis, or Ted Ginn. I know a lot of you will say Steve Smith but, at this point I think it's to close to call so i'm giving it to the younger legs.
He didn't run a 40 at the combine. He ran at his pro day and was clocked at a 4.41 and a 4.48. Mind you those are 40 times that depend on quick twitch reflexes and speed through 40 yards. He gets to be a strider on longer runs and is not as fast. He's good in small spaces because of his ability to change direction and shift. No one saw this on punt returns because he was taught, as an NFL returner to get up the field and don't, for the love of The Golden Calf of Bristol, run backwards.
