I don’t think you can compare them the same because they do different things for your team
McKenzie was a big play guy at times who was underwhelming most of the time
Sherfield is a blocking wide receiver. He’s got good size appears to have good hands is not slow.
He played behind two very good wide, receivers in Miami, and was considered their third wide receiver
I’m not saying he’s going to have 1000 yards or anything but whenever you see one of our running backs go for a huge run, don’t be surprised if it was a Sherfield it was blocking for it
