The 49ers don’t have a 1st round pick next year. They traded their 1st in 2022 and 2023 to move up to 3.
Rodgers may be 37 but he’s one of the best in the league. Losing him would take the Packers from being a SB contender to a mediocre team at best.
Garoppolo is not an exciting replacement either and I doubt the 49ers are willing to part with any of their best players as part of this deal.
There’s really not much to consider here.
