This is a good thing. Pryor isn't nearly as good at throwing the ball as Palmer and doesn't have the experience at reading defenses but that comes in time. They will both be starting off with the same amount of time with a new playbook and possibly splitting reps at OTAs and camp.
I'd like to see what Pryor has when he gets a chance with the first team. He def has escapability in the pocket. If he can polish up his throwing mechanics and be more accurate on the run, I think we would have ourselves a pretty healthy competitiion. That said, it will all depend who gets the reps in practice
