Well, considering they only have the 2 designations to return from IR, and they used one of them on Sternberger, I would imagine the kid is going to be playing a lot. Why would they waste that?
I think he is going to make some very big plays for us down the stretch. Just a feeling I've had since we drafted him, knowing fully rookie TEs don't normally produce straight out of the gate. Seriously, I've envisioned him making clutch plays for us from the moment we drafted him, and I've considered him as much a draft day steal as Savage, Jenkins, Keke... Summers... we'll see.
He's wearing the 87... he's got great hands - best in his draft class at TE (better than Hock, Fant, Smith, etc), runs great routes, is actually quite a good blocker too - not so much in-line, but in the open field, especially on run plays. All the stuff Rodgers loves in one of his receivers. Maybe he winds up becoming a bigger part of the offense than we might have thought.
Sternberger is versatile too. Lines up outside, in the slot, in-line and out of the backfield. He's got better quicks than his 4.75 timed 40, smooth in his routes, gets necessary separation. Monster catch radius. Great YAC. Elusive after the catch... he's really solid running with the ball. He played in a pro-style offense at Texas A&M, which should help him moving forward.
I think he will become a big part of this offense, eventually - maybe not straight away but through a steady incremental increase in reps, and may preclude any other WR additions via trade. Just my take on him.
Did I mention he's wearing the 87?
