Is Caron Buler for Rajon Rondo a good trade in a roto fantasy bball league?

I have been offered a straight up trade. I have Rajon Rondo at point right now, and he is giving me incredible ists and FG%. Caron Butler has always been a good contributor for points and rebounds, which I am in need of. I think that Rondo's FG% will dip soon so do you think I should accept this trade while he's still hot?
