For instance, the NFL quarterback ranking system is a joke. Nobody understands it or can justify it. Only in football would a runner with 1,100 yards on 300 carries be rated ahead of a back with 1,000 yards on 200 carries. If you use NFL statistics as a betting tool, you go broke. Only wins and losses, points and points against and turnovers are worth a damn.
Baseball has one designated hitter.
In football, everybody is a designated something. No one plays the whole game anymore. Football worships the specialists. Baseball worships the generalists. The tense closeing seconds of crucial baseball games are decided by distinctive relief pitchers like Bruce Sutter, Rollie Fingers or Goose Gossage.
