Depends on your definition of "much." A team that thinks it is a QB away would happily take Aaron Rodgers and find a way to pay him. The problem is there aren't a lot of teams that don't either have a QB or who they think is a QB soon.
But I highly doubt Rodgers's supposed "decline" would be the reason teams wouldn't take him. He just won two MVPs and is throwing to nobody behind a battered OL. He's not playing well but I'm betting the consensus would be to give him a mulligan.
He is old but I haven't seen the decline in skills, same thing I was saying in 2018. He can still run unbelievably well for his age. He can still throw. They suck but he still makes a "wow" play every week. He's just playing desperate a lot, and timing is off, which leads to slop and forcing stuff.
If multiple teams were willing to play the shell of Peyton Manning to stand around and toss ducks, there's no way somebody wouldn't take on Rodgers.
