Ohio State: Reinventing history
From my perch high in the press box at Ohio State on Saturday night, I was looking around the interior of the always-wondrous Horseshoe when I noticed something peculiar. On the facade beneath the upper deck of the north end zone, the school lists seven national championship seasons. One of them is 1970.
Some quick research reveals that in 1970, the Buckeyes finished second behind Texas in the coaches poll ... and fifth in the AP poll (which crowned Nebraska). According to the treasure trove that is College Football Data Warehouse, the title that Ohio State so proudly displays was bestowed by the National Football Foundation and Hall of Fame -- and even that one was shared with Texas.
Hey, as long as you're at it, Buckeyes, why not tack on 1969? No love for Matthews Grid Ratings? And what about that '73 banner from Foundation for the Analysis of Competitions and Tournaments? There's still plenty of room on that wall.
