I think the Cowboys would be pretty much unbeatable if Romo was their QB. Prescott is doing a nice job and deserves the credit. He manages the game well and doesn't make many mistakes. But that's where it ends. He has turned into a check down charlie. Throws for a couple hundred yards and completes his 15 or so passes. Hands the ball off to Elliot and has the luxury of that offensive line. Half the playbook doesn't exist without Romo. Down the field and Dez Bryant are non existent. Romo got in for one series last week. After not playing for over a year he marched the offense down the field throwing lasers, touch passes, deep balls, etc... 6 plays, 81 yards in less than 3 minutes. Ending with a perfect timing pass for a TD. Made it look pretty easy. That offense with that O line and Zeke Elliot would be like the 89' 49ers with Romo back there.
