In all serious, it sounds like Cummings tried to do everything he will not do in the regular season. Most of his pass game is short play action passes that catch you in the wrong spot, so deep balls seems like he either wanted to keep it vanilla as he can, or work on the things he knows his offense is the worst at...
If you run the veer, you have to be ready and able to throw it or you get beat all the time but he will use the hundley kid as a HB slot which will be most of his pass game and he was in track.
