Smith won only one less game in the regular season but for the season passed for more yards and had a better completion percentage. And doesn't make nearly as many stupid mistakes.
Win or lose, that's going to be one heckuva game... Good luck to your team!
Smith won one less game with one of the easiest schedules in the league, the Niners had more wins against teams that finished over 500 (4) than the Chiefs had GAMES against teams that finished over 500 (2, of which they won 1). Sorry but there is no world where Smith is a better QB.
