Studs not cutting it...wait or make a move?

[dg12x]

14-team H2H keeper league
Standard scoring non-PPR

My keepers from last year were: Ray Rice, Frank Gore, and Andre Johnson

Thought I'd be sitting pretty this year with 3-top 10 players in a 14-team league, but I find myself in 13th place with a 3-6 record.

QB Big Ben
RB Frank Gore
RB Ray Rice
W/R Jamaal Charles
WR Andre Johnson
WR Mike Williams (TB)
TE Vernon Davis
K Revolving Door
DEF Revolving Door
Bench: Favre, Kitna, Malcolm Floyd, V-Jax, Crayton, Cadillac Williams

Stay put and hope I come alive down the stretch, or make a move?

I've been dangled a trade of my Charles/Vernon Davis for Roddy White/Tamme, but not sure it really improves my team.

I've really been plagued by my guys just not finding the endzone, while the yardage has been there.

If I stay put, would Gore/Andre/Rice be lining up as my 3 keepers for next year as well?

Thanks for any help and WHIR!
