It certainly can work that way.....that is exactly what Nnamdi is being told in Philly.
Williams is good....overrated though. Not worth his check here. Most of that isn't his fault but still a reality.
A solid S > Williams for example....when looking at the overall good of the team. Makes the collective team better. That S doesn't have to be better than him in a vacuum.
Solid S plays every snap at a huge weakness. Williams carries can be split and taken by VERY good runners.
Actually safeties don't take half of the snaps of the team. Secondly they aren't involved in every defensive play for example if they are lined up in cover 2 on a running play. Thirdly we have safeties who came in and were decent when Nakumura went to the bench and we will be picking up another one or two in the draft or free agency. A starting running back and a starting or back-up free safety have little in common.
Comparing Williams value to a safeties value as if they are related at all is ridiculous The whole we should cut Williams and use the money on a safety was a stupid argument when you made it. Going further down the road with it makes no more sense than before. Williams is an electric game changer who scores points and moves the ball. A free safety might get 1 or 2 picks a year and at best doesn't screw up or give up the long pass. We aren't talking Ed Reed here.
Running backs play less downs than a defensive starter but they play less than a right guard as well. Anyone think that we should dump Williams to add a back-up right guard?? Running backs are impact players who are valued for what they do to change a game. Offensive guards and free safeties if they are doing their job don't call attention to themselves by screwing up.
And no I am not going to debate this on and on, just wanted you know that there are those of us out there who don't think the argument has any legs so don't keep parading it out there as if it is a fact.
