Onwenu played LG, RG, and RT as a Rookie.
LG - 112 snaps - 3 pressures, 3 hurries
RG - 185 snaps - 1 hurry, 1 pressure
RT - 616 snaps - 3 sacks, 5 hurries., 8 pressures.
Note: He played multiple positions against Denver, LAC, and Buffalo. I didn't have time to do a deep dive into what he gave up where in those games.
Sophomore: LG/RT
LG: 290 snaps - 2 sacks, 2 hits, 3 hurries, 7 pressures
RT: 276 snaps - 2 hits, 2 hurries,. 4 pressures.
I think the biggest problem that Onwenu has is that the Pats haven't kept him at one spot. His first "bad" game at LG last season was against TB. Then he was mediocre against the Chargers while playing RT. He then ended the season with a bad game run-blocking against Jax when he saw 30 snaps back at LG. He saw 10 snaps at LG against Miami and his pass blocking was trash that game.
His most snaps have been at RT. His least at RG.
Total:
LG - 402 snaps - 2 sacks, 2 hits, 6 hurries, 10 pressures.
RT - 892 snaps - 3 sacks, 2 hits, 7 hurries, 12 pressures.
I said it before and will say it again. Stick him at a position and leave him there. With Mason gone, you need to build around Onwenu and Andrews. But they need something more than Patricia/Yates for the O-Line Coaching.. Without that, then it won't matter who they have for players. Patricia = Gugs PT 2, imho.
