Help me out, Football (Not Futbol) Fans

Is this claim (the second one in the following excerpt) in a current Chuck Klosterman column accurate?

You wouldn't become a coach if you didn't believe in the inflexibility of rules. This is why baseball people are still skeptical of "Moneyball"; this is also why every pro football team not coached by Mike Martz plays pretty much the same way, pretty much all the time (the most innovative pro offenses are still just variations on the ideas of Don Coryell and Bill Walsh).

It seems a little fishy. And by the way, is it just me, or is Chuch Klosterman's writing super pretentious? (Oh wait, so is mine.)
