My mind would be more boggled if I knew how far ahead that record is of others in the same situation (besides the Romoless Cowboys).
True that 100 yard rushing games aren't an every week thing.
But, for example, I looked a couple of years back when the Giants were getting a few of them. In 2013, they had 3 games with a 100 yard rusher while hold the opponent under 28...they lost 2 of them.
Again, they lost 2 out 3.
I'm guessing the norm is to win at least 3 out f 4 though...maybe even better.
But 10 out 11 (or 51-4) is pretty crazy.
