ANALYSIS: The 49ers head into Seattle with a banged-up rookie QB under center and their best receiver out. The Seahawks defense is particularly awful against the run, so this matchup is shaping up for San Francisco to do a lot of running the football. Mason iced away victories the last two weeks, topping 50 yards in each game, and his workload in the ground game has gone up consistently the last four weeks. I believe he's going to be a bigger part of the gameplan from the jump, and as long as he doesn't drop back down to receiving just 4-5 carries, he should sail over this total. I think he's going to post a season-best mark here, so this is going to remain good value through kickoff.
