If you look at his production this year against the top defenses, our offense at large hasn't been able to dominate them and our wins are due to our all three phases potency moreso than the offense. That said, it might be coming this Sunday, but either way it's risky from a FF perspective.
I would start someone else this week. I love Goff and think this might be his statement game, but if I'm trying to win my FF league I'd go with a QB who is facing an easier matchup. I got a lot of respect for the Vikes' D.
