Athleticism can be a useful shorthand for scheme fit. While Darrisaw didn’t test at his pro day, we can surmise that he would likely have not tested as the most agile or speedy lineman. That would have implied that he is a scheme-dependent lineman — man schemes only. But athleticism is a shortcut, not the full answer. If a lineman is 350 lbs. and slow as all hell but finds a way to get to his landmark on time, does it matter how fast he is? If a defensive tackle is scooped in the forest, and nobody’s around to time his 10-yard split, does he still concede the gap?
Virginia Tech gave us some tape to see if he could pull off those techniques anyways. Darrisaw is more functionally athletic than his tested ability would have likely been.
