That is the west coast run/pass balance in a nutshell. Theyve been working on it for months. I find it dubious that they would be able to change the offense to a run oriented, power based approach in one off week- even if the players are familiar with the concepts from the last couple of seasons. It takes more than a week to make that substantial a change.
Plus, why would you think that their current coaching staff is remotely as good at understanding and implementing that type of scheme as the last one was? Its not their offense.
I think they should focus on moving forward at this point and work on the passing game.
