I don't know. Maybe the Cowboys know something I don't know....
But last year, they had their best LT, who also happens to be the best LG, playing LG. Meanwhile, the player that struggles the most ends up at LT, where his best position happens to be RT.
So what gives? Even when Dak went down, there were no changes in the offensive line where one could argue a player swap may have benefited an offense with a limited Cooper Rush. Or is it that he also likes the best protection from the LG position? Even if so, do these guys know what is best for them and the team?
I get it. They were experimenting out there. But the line could have been better if we had played our players to their strengths relative to doing so having a higher impact on the overall team.
Just my two cents
