The kid has good hands, is quick, and has made some good plays. Sure he should have run out of bounds his only mental mistake in 3 games. Both turnovers were just incredible plays and one of them wasn't exactly his fault. I've been happy with is play.
Furthermore, I have seen nothing out if Blackmon that would made me think he should be on the field at all times . In fact, I've thought he looked a little slow compared to everyone expectations.
