PFF has three stats that attempt to take that into account.
1. Cover Snaps per target
2. yards per cover snap
3. cover snaps per reception
Does PFF, or any other stats keeping entity, keep track of quality of competition? This is done in hockey where the level of competition is weighed when grading the performance of a player.
For example, if Aldon beats a run of the mill tackle for a sack, he is not given as much credit than if he were to beat someone like Jason Peters (very good LT). With the unbalanced schedule of the NFL, I think it's very important to weigh "quality of competition".
As it relates to DBs, if a CB shuts down Megatron, he should be given way more credit than if he shuts down a low tier WR.
