Congrats on your new head coach, Mike Tomlin. He sounds like an up-and-comer, but I'm not sure how I feel about the Steelers becoming a Cover-2 team (if that is what happens).
As a Bengals fan, I'll enjoy any growing pains that the club goes through. Any such transition will have at least some set backs. I also think that a 3-4 is tougher on a passing team (such as the Bengals) in terms blitzing from everywhere and making pass protection a chore. The Cover-2 depends more on the four down lineman getting pressure. Its effectiveness depends on good coverage downfield and the ability of the lineman to beat offensive linemen one-on-one. The 3-4 adds the element of suprise--how many defenders are rushing the passer and from where? We'll see.
As a football fan, its hard for me to separate the Steelers from the 3-4 zone blitz (granted, they made their hay in the '70s with a 4-3). For their sake, I hope they stick with it. They have managed to have unparalleled sucess mining the draft for guys who fit the 3-4. They have a dynamic safety in Polomalu who they move around a lot and is fun to watch (not so much so in a Cover-2 where he'd almost always have deep coverage responsibility). I'll say this, the Pittsburgh Defense is one of very few that is fun to watch. They are aggressive, it seems like all the players are big-hitters, and the scheme is anything but vanilla.
If they do switch, what happens with coordinator Dick LeBeau? How will guys, particularly guys in their front seven, adapt to the new scheme? The Cover-2 requires ends who can bring pressure and linebackers who can run and cover. Brett Keisal (5.5 sacks) and Aaron Smith (4.5 sacks) are excellent 3-4 ends, but they will have to get pressure without the aid of blitzing linebackers. Guys like Joey Porter (7 sacks) and Clark Haggans (6.5 sacks) will be dropping into coverage more than they rush (Minnesota's three starting LBs last year had 8.5 sacks between them), meaning their pass rushing skills will be less valuable. If a switch to the cover-2 happens, more than a few Steelers will see their roles diminished or be packing their bags.
If I were running an NFL franchise, I'd be licking my chops to acquire LeBeau and whomever else gets cast off from the organization (particularly the scouts who are so adept at selecting players to thrive in the 3-4).
