Given what we have at QB, I think the starting job is Raiola's to lose if he commits here. As you said, Purdy has shown some flashes, but I haven't seen anything from him that suggests that an elite QB coming out of HS couldn't play at his level, if not better. HH shouldn't be in the conversation as a starter, and Kaelin just doesn't look like a start-day-one kind of prospect. It's a scary thought trusting a true freshman to lead the offense right away, but it's less scary than rolling with what we have now in my opinion.
