I am partial but
 

I have to go with the Steelers O-line. Anytime you can get two backs over 1,000 in a season there has to be love for ya! ppls$ ppls$ ppls$ ppls$

consider Dolphins O-line
 

C-Jim Langer, Gs-Larry Little, Bob Kuechenberg; Ts-Norm Evans, Wayne Moore/Doug Cusan. Unbeaten in 1972, 2 1,000-yard rushers, 2 HOFers, helped 3 skilled players (Griese, Csonka, Warfield) reach HOF status. Dominated Minn. in SB VIII. And I am NOT a Dolphins fan!

Ok, then...I think you have to throw in the Browns with Mack & Byner. I think they both went over 1k yds. in the same season.

Dolphins: Yep!

put em in
 

I have no problem with that. Any time a feat like that is accomplished the line should get some love.
