All Chaney's testing numbers suggests he's fast, but I personally have a hard time judging real speed from high school film against high school competition. I believe they replayed his 1v1 right after the play was over and seeing this big dude ABSOLUTELY MOVIN' in HD on a big screen I did a double-take when I realized it was Chaney. Already 200+ lbs. and just a teenager, future looks bright. I can imagine as the season goes on, after Cam and Rooster cut a defense up, that Chaney comes in and busts a huge run in the second half of games.
