I would not want Rodgers over Brees if it were possible.
Outside of his TD/INT ratio which gets brought up all the time, Rodgers don't really have anything else over Brees statistically. Brees has far more comeback wins, yardage, and has done more with less than Rodgers and all while playing in the toughest division in the NFC.
I've felt for years that the Packers have had it made playing in the NFC North which usually is a mediocre division with 3 teams they can beat up against, similar to how the Colts used to dominant the AFC South back in the day. GB made the playoffs in 2016 at 10-6 relying off half of those wins from their divisional opponents. In 2015 they barely went 10-6 that year too. Put Green Bay in the NFC South or another tough division and they'd be an average team.
Brees is older and has aged better than Rodgers so far. We have the makings of an offense that can carry Brees in his older years without asking him to throw 40-50 passes a game. On the other hand, with Rodgers' injury history, no one really has any idea how he's going to age in the future. He's already peaked as a QB and his production started to go down a few years ago.
