Sorry, Eagles have best OLine in league, including 2 HOFers playing at their peak, and the best OLineman in football regardless of position (lane johnson, next year will be 3rd straight year of not allowing a single sack).
Even RBs is debateable: .miles Sanders voted to proBowl (before all the alternates started getting in).
Cowboys have huge special teams advantage....and better LBers, assuming u don't count Reddick as a LB.
BUT, that's this year. Things can change rapidly these days....one year to the next
