I would normally lean towards the stack of Baker and Egbuka. But Herbert looked special week 1 against KC. He hadn't historically been great for fantasy when he was playing KC, but it looks like Harbaugh and Roman are turning this team over to him. That, plus the matchup, I think Herbert is the better QB choice.
If you're a heavy underdog and you need the stack for an upside swing, stick with the TB stack. QJ looked good week 1, but I couldn't bench Egbuka after week 1. QJ has shown flashes before and failed to sustain it. I picked him up in a couple leagues, so I am hoping he's found something, but I'll give him the week on the bench to find out, before I consider benching Egbuka. Everything surrounding him this off-season was positive and so far it's paid off. I'm sticking with him for now. So if you feel forced into the stack because of an underdog matchup, go with the lineup you have. If you're favored or it's projected close, I would lean towards Herbert and Egbuka.
