There is a big difference in asking a QB to retire so his backup can take his place than being ready to move on because a player is older or injured. Sorry that's apples and oranges. The conversation was about asking Brees to retire so they could give it to Teddy. Absurd. Entirely different circumstances with Favre and Manning. Your attempt to make them identical is laughable.
The Packers FO were ready for Favre to leave, because they had Rogers in the wings. The Colts cut Manning and drafted Luck.
Sorry, but if Teddy was a Franchise QB, the Saints would lock him up.
There might be one “sucker GM” who will gamble on TB with a big contract, but I don’t see him sniffing a 20M a year contract.
