That kids legs are massive. He's going to grow- a lot- once he gets into college.
The thing is, his position designation matters very little. Jace Amaro was listed as a TE last year and played 90% of his snaps out wide in the slot. That's a receiver, regardless of if you say WR or TE, that's a receiver. He has the size and explosiveness to hold the S in the seam, which will open up the underneath stuff if we run verts and then dump it off, or if he runs the seam and we run crossers underneath, or if we run four verts it holds the S to the hash on his side. That means someone is singled up.
Football isn't a track event, and if it were that easy every NFL team would simply go sign all the high jumpers, but athletic ability and explosiveness are prerequisites for certain positions and a "move" TE is one of them. Stack trips to the short side, move this kid to the far side isolated on the other side and you put the defense in a tough position inside the five yard line. This opens things up for a flood underneath on the other side as well if teams shade a S or nickel LB to that side.
Certain skill sets lend themselves to scoring in the red zone and he has one of them if he can catch and high-point the ball.
