They year Kennedy spoke at Michigan was actually during the period that NW enjoyed its greatest success until Barnett arrived in Chicago. They beat tOSU a couple times during the period 55-63, when ND stole him away. I do remember the jokes, including the one riding down I-94 and noticed a driver took the time to get out and underneath in write, NW 0, but that was during the late 70s, early 80s. Misinformation can make an entire meaningless piece even less so.
Hoke was top notch at this aspect of his job.
