I agree. I believe it's harder to put together an elite offensive line than find a stud running back. Elite olines can make average rbs and QBs look good.
Well I disagree with the OL being harder to find than a "Stud" RB. Dallas has only had 3 ELITE RB's in its entire existence. Dorsett, Smith and I am going to put Zeke in that list. Duane Thomas was good but not elite. Those guys do not come around all the time. I find it funny when people think average run of the mill RB's will look real good behind a great OL. lol. No. Great RB's look good behind any OL. The list is long proving this. Barry Sanders, Walter Payton, Jim Brown, OJ Simpson, Terrell Davis, Bo Jackson, Marshall Faulk..... None of those guys had an OL as touted and revered as what Dallas has now. Yet, they were GREAT. Emmitt had a great OL but he would have still been great without one too.
So, no. Give me a game changing ELITE RB any day of the week over an "elite" OL. It isn't even that close. Hence why RB's are called SKILL players not OL. Granted, I like stud OL as much as the next guy. I am just not ignorant as some are, as to who is more valuable to a team.
