Yes I heard that he was fast but small.That's Xavier Worthy from Texas - he set the Combine 40 record at 4.21 (faster than the Cheetah). But he's only165 lbs on a 5"11" frame (there's cycling sprinters bigger than him. Lol).
He's not going to survive at that weight. Just wait until some 210 lb safety with bad intentions obliterates him. He's going from getting hit by Big 12 DBs to the best of the best of NFL DBs. Unless he falls down after every catch or runs out of bounds, I predict he'll be hurt before season's end.
