You started by basically thinking that KC last year's SB with no name guards. It's pointed out to you that their one OG was a highly paid, high level OG like Martin and now you want to talk about ranking his impact on the offense. I think it's clear you didnt realize that KC, in fact, was like Dallas with a highly paid OG.
Other than a QB, no one else on offense can really alter the trajectory of a franchise on their own. Not a WR, not a LT, not a TB, not an OG.
I am still trying to figure out what your overarching point is here. You seem OK with the Cowboys extending Martin, so what's your beef here?
99% of the folks wouldn't know the name of the guards. but fact is KC won it without Thuney and with Thuney. is that a difference make then?
am I saying Guard is a useless position on offense? no. its not. I have argued in the past, the OL works as a unit. it fails and succeeds together, where every other position you have to win your individual battle and if one piece fails, you can still find success (i.e. WRs, 3 can fail, one succeed, get him the ball, play suceeds). on the OL, if one piece fails, the whole thing fails regardless of what anybody else did. so my long winded point, I am not dismissing the notion that you can just put any bum in there.
but its about investing your money, with the limitations of the cap. do you invest 8-10% of your money in one guard. then what do you invest in LT, RT, Center. having the best guard is a luxuary. not a necessasity. if you are able to have the best guard, then great. but its not a precursor to a superbowl. Lindstrom is probably a top 3 guard in the league. are the falcons a superbowl contender? Quenton nelson is a top 5 guard. is indy a superbowl contender?
again, you need good OL. part of which is guard. having top 5 guard is a luxuary. if you can afford it. then great. otherwise, it doesn't guarantee a superbowl contender.
