It'd be Brock Purdy in and Trey Lance out if Jeff Garcia were running the 49ers ... the former San Francisco star tells TMZ Sports he's all-in on Mr. Irrelevant in 2023!!!
Purdy took over the QB1 reins after Lance and Jimmy Garappolo got injured during the 2022 season, and he instantly became a hero ... winning nine games, and nearly leading the team to the Super Bowl.
However, the 23-year-old rookie suffered an elbow injury in the NFC Championship Game ... leaving his status as the future starter in question with Lance looming in the same QB room.
