http://www.nfl.com/draft/story/8313818Saw another good read over at NFL.com, about using Combine numbers to determine things like quickness and explosion. I decided to do some research and tried to find out what I could about current/past Falcons numbers in recent drafts. Here's all the guys I managed to find.
Matt Lehr - 0.81
DeAngelo Hall - 0.66
Etric Pruitt - 0.61
Kynan Forney - 0.57
Matt Stewart - 0.52
Demorrio Williams - 0.45
Roberto Garza - 0.44
Chad Lavalais - 0.42
Matt Schaub - 0.41
T.J. Duckett - 0.38
Kurt Kittner - 0.36
Will Overstreet - 0.34
Quincy Wilson - 0.32
Alge Crumpler - 0.31
Ed Hartwell - 0.26
Quentin McCord - 0.26
Michael Jenkins - 0.07* (I saw a different source that had Jenkins shuttle at a much lower time which would have made a difference of 0.60).
I was really curious to see what Vick's was, but considering Vick ran almost no drills during the time leading up to the 2001 Draft, I couldn't find what his shuttle times were.
Of course this is not the definitive source on who has explosion/quickness, but it's just an interesting method of determining that if it's at all possible.
