Trade help Needed!

[bucs1985]

Hello, What should i do?

PPR = .5
RB/WR Flex

My Guys - Finley, Spiller, Maclin
His Guys - Vernon Davis, Steven Jackson

My Roster looks like this

Ryan
Rice / Martin / Spiller
AJ Green / Julio Jones / D. Moore / Maclin
Finley / Gresham

Finley is just not producing, and Davis is.
I have Spiller on the bench right now (but who knows when he can explode again)

I want Davis, but not sure if I should get rid of Maclin and Spiller due to the possible upside.

Any help is much appreciated,

Thank you
