I see it as kind of an ugly tradeoff. The NFL is still very much a drop back and throw your route tree league. Unfortunately, the teams that draft high (and are thus pressured to select a big name QB talent) are least equipped to succeed with that game plan.
Obviously, college teams like to use mobile QBs and RPO schemes to stress defenses and threaten the entire field. When you can set up on one hash mark and force the LBs and DBs into coverage conflicts, one defender late to his assignment can break a play into a TD. The NFL is still too fast for that. The field is too small to allow even the quickest offensive players to escape their equally speedy defensive counterparts. Thus, the NFL still covets the taller, rocket-armed QBs that can fire the 15 yard sideline pass on a rope through a tight window.
The teams drafting high, though, don't have the weapons to make that work. They'd be better off with a more mobile QB that could pick up cheap yards, convert first downs, and help out a usually substandard OL (as the true root of the problem). That style QB is not usually well regarded by an angry fan base, and would be limiting.
