The 49ers somehow scored 40-plus points yet were arguably the most frustrating fantasy team in Week 1, including but not limited to: Raheem Mostert exiting early, Trey Sermon a surprise DNP, and Brandon Aiyuk a complete no-show.
Sermon was a healthy scratch, as positive summer reports suddenly turned into Kyle Shanahan saying he’s not one of the team’s top-three backs out of camp after trading up to draft him. With Mostert unable to last one half before suffering his latest knee injury, rookie Elijah Mitchell is going to be an extremely popular waiver wire add.
