Impossible to make that comparison.... to compare 2 all time elite units, from different eras, and surrounding offensive "skill" players.
If you run a power blocking scheme, I'd take Dallas' 90 line. They could move mountains.
If your offense is based on zone blocking and movement...Eagles may have the best oLine ever for that. HOF Kelce easily most athletic C ever, even now at his age... and Lane Johnson can run OR pound...and is best oLineman in the league at any position. 3 probowlers, 2 probowl 1st alternates, 2 All Pros, 2 HOFers.
But also, to REALLY make a decision here, Troy Aikman/Emmitt/Irvin/JayNo/others from 1993 would have to jump in time machine and play behind Eagles current line, and Hurts/Brown/DevontaS/DallasG would have to go BACK in time and play behind 1993 Dallas line...to see if either offense had an uptick or downtick in play behind the other line.
TLDR version: they boff really, really good.
