Rex Ryan believes rushing attempts are more important than rushing yards. At first this seems ridiculous, but it makes sense if you subscribe to my theory of running like a boxing jab. Keep in mind rushing 'attempts' will only have the desired affect on the defense if they're usually successful.

"Five Remain on Pace to Break Marino's Record" Not really. Regression to the mean says there is no such thing as 'on pace'. But if ever there was a year to break a passing record, this is it.

That fastest possible marathon post seems to be very weak, since it's based on trends of marathon times and not on any actual model of human physiology or race conditions. At human running speeds, wind resistance is a noticeable drain on power. Imagine if the top marathoner had a tailwind through an entire course.

It's weak because it's based on actual marathon times and not a hypothetical all-tailwind race?
They take tailwinds as well as changes in altitude into account when deciding who holds the world record. The Geoffrey Mutai, the latest Boston marathon winner ran a 2:03:02 but didn't break Haile Gebreselassie's world record because he had too strong of a tailwind on a downhill point to point race.
