It's not that danged unique. Spencer makes the excellent points that Oregon's attack is a) not "pistol" based, b) not a finesse game and c) (gasp!) not that complicated. Instead, Oregon's offense produces points by the bushel the same way Barry Switzer's and Fielding Yost's* did: by putting excellent football players in position to execute a sound system. All the misdirection and threats of misdirection hide Oregon's frighteningly consistent habit of firing out, putting helmets on helmets and thereby sending LaMichael James turbopropping into the secondary.

*Ok, Yost's teams might have been helped along by playing a schedule that included Albion, Beloit, Buffalo (whom they defeated by a slim 128-0 margin) and Case Scientific. I say, did they ever put a coat of polish on the Britons that mere soap and water dare not wash away!
