Here is the difference between football stat guys and baseball stat guys. Football stat guys usually end up with stats that agree with the non stat guys. There might be disagrements of a small degree (ie who was better Marino/Elway) but rarely do I see a football stat say a guy is bad when everyone thinks he's good. The same is not true in baseball. There are players that some think are good, like Eckstein, Glaus, and Piere. The stat guys say they are not good players. This causes the rift. I bet if football stat guys came out and said Farve, Manning, and Ray Lewis were not good players and were worse than league average, there would be as big as rift over there as there is in baseball. Another difference is the quickness to change. When one football team figures out something that works, usually there are 31 other teams that have incorporated it within a year. When one team figures out something in baseball (ie OBP is better than AVG for evaluating talent), there are years after a book is written about it there are still teams, announcers, and fans that don't believe it.
