One thing about the Alex/Kaep difference is how it affects Gore. On the one hand, the Pistol is different for him, but he has adjusted. On the other hand, I do not remember Roman sticking to the run as much with Alex, and I think it is because Kaep offers the possibility of really big plays by running. Because of that, Roman stuck with the run, and Frank got some lanes, in large part because of the threat of Kaep. It's kind of like one receiver getting single coverage because the other guy is covered. Teams that have only one to[ receiver have a tougher time of it.
