Well, Jennings was a second rounder, OBJ, Watkins, and Hopkins were first rounders - OBJ and Watkins high first rounders. So their success wasn't shocking - and even then not common right out of the gate. The occasional later pick succeeds immediately, but it shouldn't be planned on.
I do hope that at least one rookie receiver makes some sort of impact - not star level initially, but a decent contributor, with Britt, Austin, Gurley and Kendricks taking the majority of targets. Hopefully with those guys doing their thing, the pressure will be off of the rookie receivers, and they can find their way to become important to the team.
