Jimmy will be on the roster until the last possible cut date unless someone makes a trade offer before Aug 30.
Even if it is Trey SZN and Trey's team the 9ers will need another capable QB who knows the offense to run drills in camp anyway. That's Jimmy. Do you really want our developing guys learning under Nate Sudfield or Brock Purdy?
It isn't like it will cost them anything additional to keep him until Aug 30.
& I know nobody wants to hear it, but if a trade offer doesn't materialize, and Jimmy G is balling out in camp, and making the plays, he could survive the cut date, it isn't like the 9ers can't afford to keep him. They can once they cut from 90 players. And it's kinda late in the game to be worrying about having tons of money on hand for big name free agent acquisitions now.
I know the Jimmy slander is strong but Kyle's offense relies on quick release and JG was still one of the quickest releases in the league. They might even keep him under contract to try to trade during the season if/when another team's starting QB goes down injured. There's a lot of options to explore, it's chess not checkers.
But they're definitely not going to run on Nate Sudfield and Brock Purdy exclusively from now until the season unless someone ponies up a somewhat palatable offer for Jimmy G., I can say that much fo' sho
