I just read Emmitt's autobiography again (which was published in 1994, right after Jimmy Johnson was fired). And what struck me was how different the game was in the 1990's. Unlike today, running back was a premiuim position.
And the stars at RB in the '90's were so much better than what is out there today (in my opinion). For example I remember watching Emmitt Smith, Barry Sanders, Ricky Watters, Thurman Thomas, Jerome Bettis, Chris Warren, Marcus Allen, Rodney Hampton, Eddie George, Terrell Davis, and Barry Foster, and those are just the ones that come immediately to mind.
