The 49ers inked Mac Jones this offseason to serve as Brock Purdy's primary backup, but the former Round 1 draftee might serve the Niners in another way.
When the San Francisco 49ers originally signed quarterback Mac Jones to a two-year free-argent deal earlier this offseason, they hadn't yet extended their franchise signal-caller, Brock Purdy, to what would become a lucrative five-year, $265 million deal.
Purdy's extension ultimately became reality, but the Niners didn't know that at the time they signed Jones, suggesting he could have been a contingency plan if talks between Purdy and the front office broke down.
