Fantasy Football, need some help!

[Halius]

So I made it to the playoffs, however I have a dilemma, the guy I am playing this week has the highest scoring team this season, although has the same record as me so he is beatable lol. I need to put together the best lineup I can, and I know some of you here play Fantasy Football so I could use some advice. I'll list my team and my bench players and you can go at it, give me some moves I could do or possibly waiver targets, let me know what you think. And this is a standard scoring league, not PPR. Anyone I have put an * next to denotes I picked them up this week and who I dropped to pick them up.

Starting Lineup:

QB: Tom Brady vs. Miami
RB: Jamaal Charles vs. Oakland
RB: Giovani Bernard vs. Cleveland
WR: A.J. Green vs. Cleveland
WR: T.Y. Hilton vs. Houston
TE: Greg Olsen vs. Tampa Bay
WR/RB: Josh Gordon vs. Cincinatti
DEF: Seattle vs. San Francisco
K: Dan Bailey vs. Philadelphia

Bench:

RB: *Jonathan Stewart* vs. Tampa Bay *Dropped Ryan Matthews
RB: *Juwan Thompson* vs. San Diego *Dropped Denard Robinson
RB: *Andre Williams* vs. Washington *Dropped Jason Witten
WR: Larry Fitzgerald vs. St. Louis
WR: Jordan Matthews vs. Dallas
DEF: St. Louis Rams vs. Arizona

The one I am debating right now is swapping Giovani Bernard with Jonathan Stewart, as Stewart could get the start again this week against a shitty Tampa Bay run defense and Gio has been slumping lately after his hip injury along with his timeshare with Jeremy Hill.

Anyways, any and all advice is appreciated, thanks!
