I'm very dubious about those numbers. A 10.3 anything would be one of the fastest HS times in the nation. I can't find a listing for Evans anywhere in the national track listings. He's obviously fast, but I seriously question he's close to 10.3 fast.
More to the overall topic it's not that LD is wrong in liking the idea of more speed but he can be awfully bad in making it sound like speed makes you a good football player. Lots of people clamored for Paige to be on the field last year because he was highly touted and, of course, fast. He was sitting then and isn't even on the team now. O'Neal actually was a 10.3 guy and, well, you know the story. Leonard Scott anyone? Any chance we learn a lesson from this?
Get guys that can ball first and foremost or even a 4.00 40 will only do you so much. People keep mentioning Coker, who, while nowhere near as fast as many believed him to be, was (is) pretty fleet. His loss was lamented as losing a "big play guy". In his 494 carry career at both here and Hampton Coker tallied 15 runs over 20yds and 5 over 40yds. That bane of LD's "speed first" philosophy, Arian Foster, in his first 491 carries had 14 runs over 20 and 4 over 40. I'm hardly bowled over by how much more of a threat to break a longer run Coker showed himself to be in spite of an obvious speed advantage. I think vision and quickness (which is not necessarily synonymous with speed) are huge factors. If you can't manage to get your speed out where it'll do you some good (Chris Johnson/Dexter McCluster/etc) you're chances to show off your NOS button will be few and far between. Same thing in a receiver if he can't run good routes and catch the ball. Wes Welker is the NFL's #1 WR in catches and #2 in yardage and if he is a sub 4.5 guy then I run a 3.7.
LD, I can appreciate you like speed in a football player. Can you at least try a little harder not to make it sound, even if it's not actually your intent to do so, that being fast MAKES you a good football player?
