Saw this on another forum, figured it was worth posting due to a few names that popped up. It judges lineman in the run game, nothing else.
The light of football science has illuminated many dark corners of the field, but one shadowy place remains: the offensive line.
Until now.
I am pleased as Hawaiian sugar-free Punch to introduce ROBIN, a metric system that isolates and quantifies an offensive lineman's contributions to the running game.
ROBIN stands for results-oriented binary metric system. Resulted-oriented means the system is based on detailed tape reviews of every run block at the point of attack. Binary means that for each of these run blocks, I assign the offensive linemen involved one of two grades: win (the block results in a viable running lane) or a loss (the defender is able to put up a road block).
By adding up an O-lineman's wins and losses, I can then calculate his point-of-attack win percentage, a holy grail metric I call POA win% (clever, right?).
Without further ado, here are the best and worst linemen from 2008 in three categories: overall, pull blocks, and second-and-third-level blocks (any block between the line of scrimmage and five yards downfield is a second level block; any block more than five yards downfield is a third-level block).
