While I don't trust Fitz the most anymore at QB, this matchup is pretty good for him. They're throwing the ball a ton, and he'll most likely get decent numbers, even if just in garbage time. Ben on the other hand doesn't have the best matchup, despite them not being very efficient running the ball. Ben will probably be a safer play (200 or so yards, TD or 2), but Fitz if you're looking for more potential.
For TE, I'd definitely go with Gronk. Second in TE red zone targets, and he's on fire. I also have to think they'll feed him the ball to break the TE TD record.
