It's kind of funny, that after the Thanksgiving game. Not only was Manning, going to break the record, he would shatter it. Some people were saying he'd reach 60. Turns out, he only ended up beating it by 1 TD, granted he sat out pretty much all the last game, but still his pace dropped off signiciantly.
It's been done before, but i think it would help the league. An NHL player, scoring 50 goals in 50 games.
