Spitfrnd,
I think you are reading me wrong, I am very old school, not at all "new age". I am a firm believer that, despite all the ridiculous rule changes, a team succeeds by playing defense, controlling the ball, and avoiding turnovers.
I watch pretty much every red zone play of every NFL game every week, and I have seen nothing in Shanahan's offensive schemes (his son's brain child) that would let Tom Brady succeed, much less McNabb or (god help him) Rex Grossman. Shanahan had two great years, at the very beginning of his career, when he had Elway, a series on phenomenal running backs, and a terrific offensive line. Post Elway, he has failed to win a single playoff game. He tries to install his "system", despite the personnel he has on the team, and, as a result, he has failed in the postseason for more than ten years.
Believe me, I am thrilled my Giants will be facing Grossman in the final week of the season rather than McNabb. Rex Grossman was a turnover machine as a starter in Chicago. Given the weak offensive line, poor quality receivers, and Shanahan's son's poorly schemed offense, I expert poor Grossman will be benched too.
