Some overall thoughts on the current OL:
It feels like the Seahawks are plugging the dike. In previous years, the Seahawks went all out with run blockers, and also featured a very good blocking TE in Zach Miller. This year, they are mixing and matching pass pro guys (Gilliam, Nowak) with speedy run blocking missiles who suffer in pass pro (Britt, Sweezy). Nowak also stands out as being not that athletic while being surrounded by awesome athletes. It definitely feels like a line that was just thrown together a couple weeks ago. This isn't how they planned it when they drew up their offseason plan in February.
The result is a line that will be bad, but not horrible, in protection. And bad, but not horrible, in the run game. Seattle's line had issues the past two years, but they were mostly good in the run game.
The biggest concern for me is that, because our line is mostly undersized, they struggle in power run blocking situations. Lewis and Carp are country strong and helped make up for this last season, but now they've been replaced by a speed run blocker and a mediocre athlete.
That said, I do expect the OL to gel over time and it's possible this could be the best pass pro OL of the Wilson era, if everyone stays healthy. And while the run blocking will take a step back, Lynch can turn mediocre run blocking into good performances.
I mostly worry about the absence of a real blocking TE. I think the reason the team moved Britt to guard to suddenly after week one was because they had a strong dose of reality for what life after Zach Miller would look like.
I also think Coleman should never play FB again. Keep him for specials, but Tukuafu is a far superior power blocker, and Lynch trusts him. Lynch does not trust Coleman, even when he should.
