no, you're giving up Prescott, giving Romo his starting job back, and still bringing in Cooper Rush as backup just like current timeline. You don't trade up for any QB. You draft Myles Garrett to get to Aaron Rodgers and finally fix our anemic pass rush. Of course you can always trade down and draft Mahomes instead of Myles Garrett, but hindsight is 20/20 on Mahomes and perhaps Mahomes would not have been current timeline Mahomes because Jason Garrett is not Andy Reid. So you draft Myles Garrett, Budda Baker*, Chidobe Awuzie, Alvin Kamara and Jourdan Lewis and worry about QB again if it comes to it just put Rush in the game.
*I put Baker instead of TJ Watt because Marinelli didn't like TJ Watt because he was a tweener pass rusher; wouldn't have liked Parsons either. But in 2017 Marinelli was still fairly popular here.
