Am I set up to succeed the rest of the season?

[Habslive]

I'm currently 5-5... leading my league in points but sitting in 7th place. FIrst and second place are both 7-3. The next four guys are 6-4, so I've been closing the gap.

12 team PPR
Here's my squad.

QB: Matt Stafford, Josh Freeman
RB: Arian Foster, DeMarco Murray, Marshawn Lynch, Beanie Wells, Kendall Hunter
WR: Mike Wallace, Larry Fitzgerald, Earl Bennett, Torrey Smith
TE: Jermichael Finley
DEF: Bears, Texans
K: Janikowski

Thoughts on how to improve this team? The thing I want to do most is drop Freeman for Palmer. But I only have 6th waiver priority and I'm not sure I'll be able to get Carson.
