From where I sit, looking at it from 30,000 feet, I'd say its effort and desire. One can also say, belief and cohesion. It appears to me that, as a team, these guys are playing with/for each other. Everybody wants to make a statement, as a team, and nobody wants to be the guy that lets the others down. I say that "as a whole", meaning the team. The running game? Did you notice in the SC game how the WR's were blocking?...How the Oline was getting to the next level consistently? The effort and desire to get the job done was "gut check" stuff. Coaching might have helped tweak the running game, but from my chair, this has been our guys simply "wanting it". Every phase, every player.
