Every Cowboy fan worships Jimmy Johnson and considers him a drafting genius. But people have forgotten how he ended up drafting Emmitt Smith by accident. Jimmy moved up in the draft's first round to get Baylor linebacker James Francis. Once Francis was taken, he had to "settle" for Smith.
But it interesting to remember that 16 players were drafted above Emmitt Smith.
