Playoff Challenge Roster Help

Our league is a "one and done" so once I play a player he's finished for the entire playoffs.
It's QB/RB/RB/WR/WR/WR/TE/K/DST

QB-Brees, I think this will be his biggest game of the playoffs

RB-Charles/McCoy/Gore, Obviously I could play the two studs but Gore has a excellent match-up especially since Forte just ran all over GB. Given up over 85 points to RBs the past 3 weeks.

WR-Green/Nelson/Allen/Jackson/Colston/Crabtree, may save Green for next week and I think the SF/GB game will have tons of scoring.

TE-Graham/Davis, both have great matchups

K- Dawson/Vinatieri

DST-Bengals/Colts, Bengals seem like the solid play but the Colts defense has been great the past 3 games. Best fantasy defense the past 3 weeks. 50+ points

I put the plays in bold I'm currently starting. Any moves I should reconsider?

I really want to play Gore, I think he gets 80+ yards and 2 TDs
