Good point sir..

I would think that about the one position that takes the least understanding of the current scheme of a team is nose tackle.

You could put Rubin in at nose, and slide Peko and the rest of the NTs who already understand the scheme to DE.  Rubin would be in his element, aka run forward and maul whoever is in front of you when the ball is snapped, and we have a trained NT at DE who at least understands the concepts.  Peko would know, as hes the 10+ year vet we brought, and understands the game thoroughly.

I know how far fetched this hypothesis is, and how safe and methodical Elway has shown to be, however it would change the tactical aspects of the game.

It would help reduce the strongest aspect of the Dallas attack, the running game.
