GREEN BAY, Wis. -- There's perhaps no more competitive -- and no more telling -- drill in Green Bay Packers' training camp practices than the one-on-one pass-rushing/pass-blocking period.

While it is not the only measure of an offensive lineman's ability to protect his quarterback or a defensive player's prowess as a pass rusher, there is a winner and loser on every rep.

And from time to time in our Packers daily camp reports, you will see references to a player's record in the drill.

Periodically throughout training camp, we will compile those records in one place to give readers a better idea of who's doing well in the drill.

But it's important to measure more than just won-loss records. To dig deeper into the numbers, we once again turn to reader Luke Stanke -- a Green Bay native and graduate student at the University of Minnesota who has an interest in statistical analysis. Last year, he used a formula similar to the Ratings Percentage Index (RPI) employed in college basketball to rank the players based on my results of each head-to-head matchup.

This year, Stanke, who has helped me with the ratings since 2011, has added a metric called block rating. He explained it this way: 1) the performance of a player in previous years, 2) the quality of the opponents a player has faced in the drill this year, and 3) the skewed success of offensive players in the drill.

The chart below shows the records and ratings.
