I don't know about switching to 3-4. That's a whole new learning curve for everyone in our defense. I say stick with what made our D successful and make improvements to it; such as adding a pass-rushing DE, possible replacement for Smoot.

why would we change something that is going great? the 4-3 worked wonderfully, i see no reason to change

[QUOTE=Kevikazi]I agree that our LB corp is excellent, but I'm still concerned that we aren't able to generate any kind of pass-rush from just our front four in consistent basis. In my opinion, if we get a solid pass rushing DE (or two), our defense will dominate for years to come for sure.[/QUOTE]
The big thing with Williams D is unpredictability. Our sack leaders this season were a DT and a CB! Not a DE or LB (granted, Lavar didn't play most of the year). While I agree that a true pass-rushing DE would help, I don't think they should go after any big names or anyone expensive....draft or pick up someone young that Williams and Blache can mold into the perfect DE for this defense.
