With Cleveland moving on from Manziel, it's highly likely they take a quarterback and it'll probably be Goff so he'll be off the board when we pick. I guess it depends on how Jerry and Co. feel about Lynch and if he's worth taking as the number four pick. I personally feel like he's a project and could benefit being on the bench for a couple years to learn and develop. The Cowboys have plenty of options on what to do with the pick. You could take a guy like Bosa to strengthen the line, Ramsey to improve the secondary or take Jaylen Smith or Myles Jack to help the Linebacker core. Hell, Treadwell could be an option too as the number two receiver, but I think the coaching staff is comfortable with T-Will. They could even trade back and get an extra pick in the first or second round.
I personally would try and trade back and attempt to get a second first round pick and take one of the guys mentioned above as well as Carson Wentz. I would love to get him in the early second round, but I don't think he'll get past the Texans. I think Wentz would be a perfect guy to get and let him sit behind Romo and pick his brain.
