Test question: You are an NFL offensive coordinator, and for your next play, you have two basic options. Put the ball in player A’s hands, and expect, on average, 4.7 yards, or give it to player B knowing the average gain will be 7.4.
It seems rather simple. Even if you factor in the situation, you want to gain more yards, right? Oh, sure, you will have to mix things up at times because defenses adjust and you have to keep them uncertain what is coming. But over time, you would expect to lean towards B. Even make him the real foundation of your offense.
