Cam Ward might be a franchise QB, but he'd have a weak line and no legit #1 WR. We'd be better off going the Houston route to build the lines first m, get the weapons, then get the QB.
If you think he's a franchise QB you have to draft him. You don't have to start him right away. Let Carr start for another year if you can't improve the line and receiving room enough but you can't pass on a franchise QB.
It's like having the choice between Lattimore and Mahomes. Lattimore is great but Mahomes changes the franchise.
