Straight ahead for the first 20 yards, Cannon is on par with Light, Mankins, Koppen, and Kaczur. For the first 40 yards, he's on par with Light, Koppen, and Kaczur. For the vertical jump, he's an inch behind Mankins, 1.5 behind Solder, and two better than Koppen. In the broad jump, he beat Mankins, Kaczur, and Koppen. His 3 cone time beats Koppen's. The only real lacking number is his his shuttle time, and it makes sense that a 360 pound guy isn't going to change direction overly well. Still, it was on par with (299 pound) Rodney Hudson, Will Rackley, Jason Pinkston, and not too far from Willie Smith.
I think we're seeing Belichick try to make an offensive line that equals the line of old (Light Mankins Koppen Neal Kaczur) in athleticism, yet adds a lot of power. For example, I'm pretty confident that 330 pound Solder would be more athletic than 33-year-old, 305 pound Light. Vollmer should be able to get up around 340 and still be just as athletic as Kaczur. At 360, Cannon won't match Neal's athleticism, but he can get close. Add a new center (Brewster 2012!) and resign Mankins, and the line is suddenly just as athletic as the one a few years ago, but 120 pounds heavier and more powerful.
