Several big name, top dollar players (and even more this year) but marginal players all over the field. They have very good OLB's now but no starting quality ILB's. All-pro at corner but very poor safeties. The o-line suprisingling is working with this methodology, but they are now only one deep at TE (could have signed Fells).

You can really see how easy it is to attack this defense - run up the middle - throw to the middle, etc. There's no talent there once you get past the LOS. Better linebackers and safeties would have been able to shut down a lot of what San Fran did. Not rocket science.
