I have no idea what kind of a blocker he is, but I would hope any deficiencies in that area would not keep him off the field if he could be Mr. Devastating Slot Receiver.I don't think so because we'd just be using him as Gesicki in that scenario and look how many passes went his way. Sherfield is on the field because he can also block very well, something that Berrios can't do.
If we have Hill and Waddle on the field, I want every other receiving target to be great at blocking.
