PITTSFORD, N.Y. -- One of the highlights of Buffalo Bills training camp practices in full pads are one-on-one pass-rush drills.

The concept is simple: A coach stands where the quarterback would, and, on a whistle, one offensive lineman tries to keep a defensive lineman at bay.

It's a chance for coaches to assess technique on both sides of the ball. It's also a drill where one rep can vary significantly from the last. But when viewed as a whole, trends develop.

We kept track of "wins" and "losses" -- these are judgment calls, sometimes -- in Sunday's drill. Here are the highlights of the results, noting that each player didn't receive the same amount of reps:
