A strong OL is the most important thing to have on offense besides QB
Show me one team that ever won anything because of their OL and not their skill players. You can't.
OL no matter how good they are can't make an average player into a star and it takes stars to win in this league. Hell the Patriots traded away their best OL and won the Superbowl.
I will say the OL's weakest links can't be bad players or else the whole offense suffers, but the reverse doesn't make the offense great.
Weeks 3-10 of this season are further proof positive of that.
