Hey man I know your bro is a good ballplayer in all, but 4.5 speed is professional speed. Your top NFL backs run around 4.5. I have seen him run and he dont have that kind of speed. He is fast for a high school kid but he is not a 4.5. If he is he should be tearing them up in track. Im not taking anything away from him, he is a good back. he is definately not a 4.5. Didnt he get timed in a 4.7 at that camp or combine? Lets get back to reality!
