Your point on the Pats' O-line is spot on. Matt Light has looked weak in the first two games. On the D-line, I might disagree, simply because the Pats haven't had a pass rush since I can't remember and Seymour is overrated. He was the 3rd best on that line after Ty Warren and Wilfork and didn't play hard on every down. Even in the 16-0 season, they were getting torched by deep middle routes because they couldn't rush the QB. The only reason they went 16-0 was that they could pretty much outscore anybody, and those skill players are now 2 years older and I for one am not certain Joey Galloway is an upgrade over Jabbar Gaffney.
That said, I still think they can beat the Falcons who don't have 2 shut-down cover corners like the Jets, so blitzing will leave Brady with more quick-hit options.
But, then again, I think like a fan.
