Arguably, the stat most associated with Dallas Cowboys running back DeMarco Murray is that during his first two seasons in the NFL, the Cowboys are 9-0 when he carries at least 18 times in a game. Now, that’s largely because the Cowboys played well in those games and ran Murray to control clock and hang on to a lead.
This is how the article originally opened. This part was later deleted from the OP, and this kind of stat is usually dismissed out of hand (as the writer did here), but there are probably better stats that can be used to measure the importance of the running game.
Over Romo's career, in games that are close through three quarters (7-point margin or less) the Cowboys are 20-11 (.645) when they score a rushing TD, and 14-18 (.438) when they don't. These are close games only, so it's not a stat that's skewed by a team having a big lead and then playing it safe by running the ball and scoring against an already beaten defense. In those same games, the Cowboys are 29-24 (.547) when they score a passing TD, and 5-5 (.500) when they don't.
The Cowboys have been almost 50% more likely to win a close game when they score a rushing TD, and only 9% more likely to win when they score a passing TD.
