The Cardinals ran the ball a lot more in the playoffs (28 attempts per game) than in the regular season (21.25 attempts per game). But the reason Kurt Warner still put up awesome stats in the playoffs was because the Cardinals only averaged 3.3 yards per carry in the playoffs, which made it impossible for Arizona to win without big numbers from Warner.
If that actually happens, Warner won't come anywhere close to the 4500 yards he threw for in the regular season last year. It's a big if though.
This is neither here nor there fantasy relevant but this was my exact argument against analysts claiming "the Cards have found a run game" in the playoffs. No they didn't. They just ran it more. They weren't any more effective. They still averaged 3.3 per carry which was the worst of any playoff team I think.
