Yeah I know. Sometimes the unexpected happens. Our team could be better than we thought. But Miller would have been a risk. They weren't willing to take that risk. The majority of the league, not the Cowboys, make moves based on the previous season.
The risk is signing Randy Gregory, a less reliable player, than HOF bound just helped Rams to SB Von Miller.
The risk is signing the less talented less catalytic Dorance Armstrong because Stephen Jones insulted Randy Gregory and he refused to take lowball offer with unreasonable contingencies over signing the more proven still leading SB caliber defenses Von Miller.
Signing Von Miller would have been akin to the Charles Haley acquisition in the 90's that catapulted Cowboys into SB champions.
Von Miller + Micah Parsons would have made this defense SB caliber and elite beyond any other defense in current NFL.
Let me say it again, Von Miller opposite Micah Parsons would have made this defense UNSTOPPABLE.
