Sure he would. How many teams do you think would be thinking "is he better than what we've got"? It would depend on the cap and what they have committed to the present #1.
Now, would they be willing to pay him 35M per and give up 2 1sts to get him, that is doubtful but if he's on the market, some team would sign him up as to compete for the job, at worst case.
Ya know, if posters would stop dogging him for not being elite like Mahomes, Rodgers or Brees and appreciate him as a good QB and leader that can move the offense and forget the damned contract.
If they didn't disclose what players make and get posters involved as capologists, the large majority of the Dakaters would back off. Forget the money and just focus on the job the player does. He wasn't the reason this was a .500 team last season.
