Honestly, anything could happen. They could all be aweful. Or maybe we got lucky on two third round picks in back to back years.
Sternberger has to be the most inexperienced and unlikely to succeed starting tight end in the league. That's not to say he's proven to be a bust, but we have no clue. His most consistent talent in his shortened 2019 season was his knack for space/move blocks. Might have a little kittle in him in that regard. Runs well. Caught a couple passes. He's a total question mark outside of being a talented move blocker
Lewis is mostly a short yardage player at this point in his career. Extremely limited in that he can't run.
Deguara is a rookie. Shows tenacity as a blocker, speed and ball skills at the college level. The NFL is not kind to rookie tight ends and as a guy who profiles as a multi-positional player, you almost have to expect him to get a slow start and be overwhelmed.
The two young guys could be long term hits for Gutebag, but multi-positional guys who have so much on their plates, it's hard not to picture them struggling. They're a year away, if they're good at all.
I can envision AR and Flower making it happen with the WRs and running backs. I don't think our tight ends have enough experience to really open up the run/pass offense that Lafleur wants to run. Im guessing we'll see an offense more like last year's with Lazard and the running backs being the improvement. Also, Jace a run blocking upgrade over Graham. I don't expect we'll see SF style run/pass proficiency because we don't have no kittle and juice to open it up. In the long run, you see what they're trying to do with Jace and Deguara though. Tenacious blockers who excel in space, run and catch
