We don't want Pitts and really we don't want Gesicki. At least not if we are serious about running a RPO based offense with Tua.
Keep in mind we have to block like every play is a running play. We have to sell every play as a RPO play. That pretty much means your TE has to at least pretend to block every play, and when he catches the ball, it will mostly be a slip out and sit down into a soft spot in the zone. We need a guy who can block well and understand the nuances of the game to find those soft spots. Then use his size to block out defenders and get those easy positive yardage plays.
Sure, every now and then he will run a vertical route but that won't be the mainstay of his game. It seems like that is about all Gesicki is good for IMHO.
So we don't need those guys. We need someone more along the lines of Pat Freiermuth. Truthfully our TE doesn't even need to be that good. We need the better talent at WR and RB. In particular our RB's need to be well rounded and be above average at running, catching, and blocking.
One thing we don't need, is anyone on offense that is a "tell". Our WR's have to be capable blockers. The main goal is to pull a safety into the box, then run a vertical along with a deep crosser/post, and force the remaining safety to pick one side of the field or the other. That is when backs and TE's will slip into those vacated areas too.
So yes, we need guys with speed. We need guys that can get separation. We need guys with YAC ability. But what we really need are smart well rounded players who can FOOL you into thinking they are doing something different than what they actually are. Grant and Gesicki aren't fooling you into thinking they are there on 2nd and goal from the 7 for a power run play.
