well one reason he could have ran a 4.57, bad form, you are in a 3 point stance and have to come out of it, running on the football field is different than track, plus nerves. Blacks want to claim they do low on iq tests because of the pressure, well theres the pressure for Whites to be sub 4.5
EDIT: white lightning beat me to it about the form
I was thinking the same thing about the possibility of the pressure, knowing that they are considered inferior and have to prove themselves. I saw some study where white students were told right before they took a math test that Asians do much better than white people and they would be getting compared to Asians....their scores dropped something like 15%.
Tebow had a decent time, but what I consider most impressive was his start. When he took off I thought, "wow, he's looking fast," and the commentator pretty much said the same thing, then Tebow seemed to slow down the more he ran. You'd much rather have a guy be faster in his first 10 yards than last 30. You combine that with his vertical and it shows the explosiveness that will allow him to be at least as effective as Vince Young running the ball in the NFL.
