I screwed that one up. I confused the 1958 and 1959 seasons up. Jake Gibbs, the guy that punted that ball to Cannon in 59 went on to play catcher for the Yankees the following year. That was a split championship in 1958. It was LSU and either Idaho or Iowa. Can't remember.
There was no split. Technically, yeah, some n00b writer's union named Iowa national champion. The people that mattered at the time unanimously named LSU as champion.
