This Saturday No.1 plays No.2. LSU vs. Alabama.
It is very rare for 1 vs. 2 to occur in the regular season.
In the past, such games drew abundant national attention and were often dubbed the Game of the Century.
The first for me was in 1966 (I was 13). There was wall-to-wall hype by all media outlets of the time. Notre Dame vs. Michigan State.
My recollection is that I listened to game on the radio. For whatever reason, I didn't watch it on TV. Maybe it was not shown in San Francisco.
The game became infamous for Notre Dame which rallied back from a 10-0 deficit to tie the game. Late in the game, ND had possssion of the ball and sat on it. Just ran out the clock instead of trying to advance the ball into field goal range.
Despite the tie, ND won the national championship by crushing USC the following week.
Of note was the talent on the Michigan State team. 4 players picked in the top 10 of the NFL draft. Not sure if that has happened ever before or after. Most famous was Bubba Smith. Others were George Webster, Gene Washington (Vikings not 49ers) and Clint Jones.
