I think the thing that's key beyond the OL, which itself is another thread is separation vs a physical group of CB. If a team can jam our WR off the route and they can't separate then regardless of the OL they will get pressure.
While I don't at all disagree with the OL being important, to me establishing a run game and sticking with it is the whole key to their offensive success this year.
PS
I saw RB post on shout that ranks our WR 2nd to last, I think that's a bit Debbie downer but they are NOT top 10 in any way, shape or form either.
