That's my point. If your plan 1A is Cousins and he would rather take less to play for Denver, you're onto plan 1B. If your plan 1B is Darnold and the Colts find a better trade partner or don't want to trade at all, you're on plan C. Which is McCown, 2 bodies, and a couple of DL in the first.
We don't control our own destiny here by a longshot. You know what team can pick anybody they want? The one with pick #1.
