I posted this in the Bart Scott thread, but frankly that thread sucks and I didn't want it getting lost in there. So here are my thoughts on this matter: It's kind of like a DDoS attack with these defenses versus Brady. The truth of the matter is, the Patriots O-line isn't good. It hasn't been good for years. Brady has made them look far, far better than they are by making excellent pre-snap adjustments. However, when facing defenses that keep things in constant motion -- that require too much monitoring all the way up to the snap for even Brady to calmly process -- he will get mentally overloaded, and the O-line will get beaten because it doesn't have the physicality or athleticism to compensate for a breakdown in the protection call. Look at teams that regularly beat the Ravens defense. It's teams that are more physical, that can adjust for a missed protection/block call by simply being bigger, faster, younger, stronger. Or a QB (or RB) that is just damn hard to take down (give Roethlisberger his due). The Ravens (Ryan) style defense is the mirror of the Brady style offense. It's extremely intelligent, relies on everyone being in sync with one bark of the field captain, constant pre-snap adjustments and concealment, and a great deal of athleticism to make perfect execution look like near magic. But it all starts with a very beefy line that has the talent and intelligence to react when things go wrong. The Pats defense isn't their problem this year (it was blatantly the problem through most of 2007 and didn't step up to the plate when it counted in the SB). Other than Brady, and his timing with his receivers, it's entirely, 100% the o-line just not being very good without Brady thinking for them.
