Wow! That's good stuff!!
Sorry to harp on this, but drops are not good, especially, if as noted in the article, the QB is trying to mess with the pace of his throws to make an on-target throw more "catchable". That will not end well.
Another thing that drops do is extend the game by stopping the clock. In the early 4th quarter so far this year, ISU has been leading all the games, and when you are leading, you don't want an extended game. The college play clock is 40 or 25 seconds depending on the scenario, but assuming an average 30 seconds can be run off the clock per play, 15 clock stops on drops equates to 7.5 minutes of extra game time.
Also, if you lack depth relative to your opponent, particulalrly on defense, I would suggest that you generally don't want to extend the game either...since drops often tend to stall offensive drives and put the defense back on the field.
