I want to switch to the 3-4. It would extend Briggs' career, fit Greene better, and give Shea one last chance So what do the current Bears look like in a 3-4 Melton and Wotton at DE. Peppers and McClellin at OLB, with Peppers probably also going in at DE some. Bostic and Briggs in the middle. Might as well just let go of Anderson and Williams since their contracts are up . Paea is stuck not fitting really anywhere but could probably situationally play NT or DE depending on situation. Definitely need some additional OLB and a true NT. The good news is our offense doesn't stand to lose a lot next year with I believe Slauson and Garza being the only FA question marks, and the biggest missing piece probably being a speedy slot receiver, so you should really be able to commit some resources to revamping the D (even if we stay in a 4-3). Obvious you have to lock up Jay too but I'm taking that as a given. Paea should work as a 3-4 DE, rotating to NT when the NT needs a rest. I think you have to bring back one of the free agent LBs because one of the reasons you consider switching to the 3-4 is the depth at LB. But are any of them really OLB in the 3-4? Williams has 3-4 experience and I believe played inside when he did. Briggs, Bostic, Anderson and Greene all seem like ILB to me. Bostic and Greene are maybe athletic enough to get by on the outside, but aren't really prototypical 3-4 OLB. So I see a lot of 4-3 LB depth. As far as Tucker goes, I'm willing to give him the benefit of the doubt. The big thing I liked about him was he talked about wanting to keep up the turnover creation, and thus far we've mostly lived up to it. His track record isn't great, but he also has never had great players really. He does have 3-4 experience too, so we could experiment with a mixed defense with him, and based on our personnel could probably handle it with just a couple additions. I'd give him another year with a couple new young faces to help the defense and evaluate again. If he doesn't improve the defense enough next year, I don't think you've lost a ton in that one year, as long as this off season you are putting the commitment into bringing in new players. Its a shame Marenelli didn't want to stick around, although maybe he saw the ship sinking and correctly jumped ship when he could.
