Ah ha. Here's what I was looking for.
Let's take the 49ers 5 SB teams.
81 - win the SB with Ricky Patton (half of you saying "who?") rushing for a whopping 543 yards. Well, I guess they did have a rushing threat. Earl Cooper added another 330.
84 - Niners are a very balanced team with Wendell Tyler rushing for 1200+ yards and a young Roger Craig adding another 500+.
88 - Roger Craig has 1500+ yards.
89 - Craig has 1054.
94 - Ricky Watters leads the Niners with 877 yards.
So...
In of the Niners 5 SB wins, twice, they don't even have a 1000+ yard RB, which we all know isn't really that hard to do in a 16 game season (more than half the NFL has a 1000+ rusher on an average year in the 00s).
Sure, the threat of being able to pound the rock is nice, but what really beat the Pats in '07 was better coaching, not the running game. Watch the game again. Coughlin outsmarted Belichick. It was like a chess match where someone knocks off the champion.
