Quarterback: Mac Jones (86 snaps)Game grade: A At one point, Jones dry heaved on the sideline. Then, near the end of this 86-snap marathon, Jones’ forearm cramped up — so he started eating bananas on the sideline. But Jones gives the 49ers a rare luxury: Breathing room to allow for Purdy to heal in toe-tality. And even with the lack of running room, he’s on track for his second 1,000-1,000 (rushing and receiving yards) season. And the Rams, whose special teams unit was ranked worse than the 49ers entering the game, lived up to that billing.
