I was just fumbling around on the SB Nation NFL main page, and found a great article about the 'tilted nose tackle'. It's actually something I've seen before first hand, playing center in high school against a formation with the tilted nose (although I think the D-Coord. called it a slanted 1-tech: same thing really). Bucs Nation wrote a great piece describing the position and how it forces double teams and allows for more effective stunts. I'll let you guys read it.
What I wanted to get at was the relevance of it for the Dallas Cowboys. The tilted nose originally showed up in Pittsburg back in the 70's with Mean Joe Green manning the position. He used the angle and his quickness to shoot through his A-gap (space between the center and guard) and wreak havoc in the backfield. The position then was repopularized by Tampa Bay, during the Monte Kiffin Tampa 2 days. It was something installed by Tony Dungy, a former Steelers defensive coach, but is now in the repertoire of Monte Kiffin's schemes.
So, could this be what the Cowboys have in mind for our DT's? I think Jay Ratliff fits the description (stocky, explosive, agressive). But with Jerry Jones talking about him being the prototypical 3-tech, maybe Jason Hatcher then. Still, this would definitely be something to watch for. I think with the correct personnel, it could be a killer position for the scheme.
