A brief discussion of blitzing over at Football Outsiders, along with a link to a Bart Scott interview where he discusses the difference between a true blitz (bringing more than 4 rushers) and just using a pass rush where you change where the 4 rushers are coming from. Some numbers are included on the top blitzing defenses in the league-- as one might expect, the 'Boys were the #1 defense in the NFL in terms of number of times they brought 5+ rushers. (This is only on passing downs-- run blitzes are not included.)
