I disagree.
While the arguments for transitioning to a 4-3 alignment aren't particularly compelling, the arguments for staying with our current 3-4 aren't particularly compelling either.
On this defense, there are only three players who rank between very good and elite: Sean Lee, Jay Ratliff, and Demarcus Ware. Everyone else, outside of perhaps Mike Jenkin, is a marginal talent at best, the proverbial JAG. And they're going to be marginal regardless of which alignment they're in.
I certainly understand the trepidation in moving to a 4-3; Ware has earned his reputation as one of the best defensive players in league playing as an outside linebacker in a 3-4. However, Ware is talented enough to thrive in any almost any scheme in which he rushes the passer.
Furthermore, in my opinion, Jay Ratliff is actually better suited to be a defensive tackle in a four man front. And Sean Lee would excel as a middle linebacker in a 4-3 scheme, especially one that played copious amounts of cover 2.
Switching back won't be easy. But staying with it won't be easy either. The Cowboys simply lack talent, especially on defense.
