Going against the No. 1 Seed and think I have a solid chance, but need some help on my flex and defense. I'm tilting big time

Flex
Tyrone Tracy - bum knee, terrible team that will only score 14 points, tough Falcons matchup

Patrick Taylor - Next guy up in SF. They are getting so far down the depth chart now though, I'm not sure they'll give him all the work. Starting LT is also out

Pacheco - Sharing too much with Hunt, tough matchup

Watson - So hot and cold, in a roulette of WRs every week, easy easy Saints matchup - they could get up so much they won't throw

Freiermuth - Pickens out, he's been more involved, but can I really start two TE's in the semis?

DEF
Atlanta at home vs NYG - Decent defense, terrible giants team, rookie QB starting that could amp up the team, but could also be terrible and put them on the field more

Bills at home vs Pats - Decent defense, terrible NE offense, cold weather game with some wind. But they've given up over 40 points in each of their last two games (granted it was the lions and the rams who are getting hot at the end here)
