Vince Young doesn't get his rushing yards by "flying." He has good acceleration and open field moves, but whoever says he can "fly" is wrong. Maybe the fiesta bowl announcer thinks 4.5 is flying for a white guy. But whenI think of flying, I'm thinking 4.3. That is flying. Anyway, its semantics.
On a related subject, I noticed during the Louisville/WF game Brian Brohm scrambled up the middle for 2 yards, the announcer promptly says he's not going to make anyone forget about Michael Vick. (BTW, if I'm playing the QB position and it reminds people of MV, I'd be more insulted than complimented.) Anyway, the very next drive, Brohm makes a good scramble for about 8 yards, the same announcer says "he's surprisingly mobile."
Brohm is about average as far as mobility, but here is how an insult and a compliment work together to enforce the caste thinking.
Q: Why is he "surprisingly mobile?"
A: Because he is white of course.
Ever hear a black QB referred to as "surprisingly mobile?"
