It's yet to be seen what BB has in mind for defensive scheme(s) this season, but count me in favor of all the 4-3 speculation. My guess is that BB will be running all kinds of hybrids and variations from 3-4 to 4-3 and beyond, but here is what I like about the 4-3: it's more aggressive. It's also more fun to watch from a fan standpoint vs. the contain-oriented "bend-but-don't-break" 3-4. It's comparatively high-risk/high-reward, but if it WORKS, we'll see more three-and-outs, shorter fields for our offense, and perhaps less need for elite speed at WR. I'd be surprised if BB makes a radical change in the base defense effective day one, but you never know. Just imagine if Haynesworth really comes through and we add another beast to the mix like Tommie Harris. There might be an opportunity for the Patriots to field a truly dominating defense unlike any other we've seen in BB's tenure.
