I think that we continuing as primarily a 43 team. However, I think that we would be fine as a 3-t team at this point.
Ninkovich-Knighton-Long
Collins-Hightower-McClellan-Sheard
I think we are one DE short.
If somehow BB got Miss ST Chris Jones in the draft, I would say yes, using Alan Branch or maybe Trey Flowers with some weight on as a weakside DE in the 3-4, because the linebackers add up.
Frank Kearse has 3-4 DE experience I believe from the Skins. It's not impossible, but by releasing the DTs this year, I thought something was up. Something tells me BB had Hicks pegged as a 3-4 weakside DE in it, but Hicks took the money instead.
3-4 DEs, you want range with the arms and some girth there, a la Seymour, but it's hard to get as is NT, but we have Brown and Knighton, so that part is covered.
Last time BB ran it regularly was 2010, but I think we are 1 3 down DE short at this point.
I still say it's in the works because I truly believe McClellin screams 3-4 WIL and it's why he was signed to a 3 year deal. Think Bruschi when he was out of position at 4-3 DE and OLB, only to thrive at 3-4 MLB once finally moved there.
Right now as the roster is, the best 3-4 look would be this:
Branch, Knighton/Brown, Kearse
Nink, Hightower, McClellin, Collins
Branch is big at 6'6 but he doesn't have "range", so to speak with the long arms.
Valentine might be able to be worked in as a 3-4 DE. At 6'3, 320, he's a bit short, but he may have the arms and power for it.
The problem with the 3-4, IMO, is to get the front 3 to buy into the concept, because it's pretty damn unforgiving. The LBs get all the glory. Between that and the fact it's hard to get good DEs and the NT in it, it's tough to run, which is why it's rare.
