Mac Jones stepped in for a sidelined Brock Purdy and threw for 279 yards with 3 TDs in a 26-21 win that pushed the 49ers to 2-0. The performance ignited a flood of “what if” takes across outlets, pitting Jones against Trey Lance and sparking Montana–Young comparisons. Jones flashed upside, though the opponent was Saints-draped by a shaky last-year yardage tally. Purdy’s health looms large as San Francisco weighs its long-term QB path.
