As for Mike Salfino’s article that I mention: It’s here, based on research from here.

Pretty interesting stuff. I’ll say, though, that I’d also like to see the Jets’ per-attempt yards yielded when blitzing, since sacks don’t factor in to QB rating. But I buy the data that suggests Manning is less susceptible to the blitz than others. Dude’s like a quarterbacking robot; there’s only so long you’re going to be able to confuse him.
