Right. And you also have to look at how Reich utilizes position groups. Would he rather have 4 receivers on the field at a given time or two (or three) tightends and a runningback or two? I'm going to say the latter more than the former, because of that versatility with his tightends and backs, and his desire to run the ball down a teams throat. Campbell certainly changes things from a positional standpoint in that argument, but nevertheless.
If that all means having an extra tight end on the active gameday roster over an added receiver, I would think there is more value to this offense there. The pass catchers are deep on this roster now across multiple spots. Mo Alie-Cox might be rolling into this season with a much higher value to the offense at TE3 than anyone is at WR4 and 5.
