Should have 4 QBs as the ps rules allow a protected QB and easy elevation on game day.
1) a vet: Rodgers, Cousins, Rudolph or whoever they want for that role
2) a true backup: if Rodgers comes back

then Rudy is likely this guy (unless a younger guy steals his lunch for the role)
3) developmental QB: Howard or draft pick whoever wins the gameday roster spot
4) developmental QB: protected on the ps (loser of Howard and draft pick battle)
A minimum of 4 QBs with 2 young guys is necessary imho…especially if a dinosaur (Rodgers/Cousins) is QB1. If Rudy is the vet guy then 2 young guys competing with him is plenty.
Rodgers would be just another delay in actually addressing a huge gaping hole on the roster.
Beta Rooney will likely let Rodgers do whatever he pleases though…so smart proactive moves matter not. The predictable will likely unfold.
