For his sake, I hope you are right, but here is the official numbers I pulled from nflexperts.com (pay site). Thier stuff is usually right on, so I assume this is correct.
I saw the NFL network replay and he surely didnt run a 4.3 anything. They said his official was 4.5 + for each. Their unofficial wasn't even a 4.4. I saw addai's too and there was no doubt he and chad jackson were in the 4.3 range. Jackson's unoffical was 4.28 and it certainly looked it.
I thought Vaughn would have done better as well -- in all categories. The 17 reps is odd, though I guess it can be misleading. I have no idea, as I lift weights but hate every minute of it and am NO weightlifter! I hope you're right, but I just don't see it. I tend to think he's best suited for a career other than football. Who knows though, maybe the Pats can draft him and work their magic like they did with Randall Gay.
