What you have to keep in mind is the number of pass attempts by Brees is higher than every other QB in the NFL, so you must look at sacks per attempt, instead of just sacks as a number by itself.
In that regard, we have done a good job, but the misleading part is the number of pressures on Brees has gone up from last year. I would say by about 25 percent. So it is somewhat significant.
I would say the protection for Brees has definitely improved from early in the season and we are on our way back to being a dominant O-line. We have also seen the emergence of Chris Ivory as a potential 1000 yard rusher, which is crazy to fathom, given the fact he didn't play much early in the season.
The penalties need to stop, however. They are trending that way.
FYI, if that list has the Colts as #1, then the list is pretty much invalid. Manning has been pressured this year like nothing he has seen since 1998. They are not taking into account pressures on the QB and QB hits.
