Playoff push

Sitting 7-1 and in first, 16 man full ppr. We only start 1 RB, 1 WR, 1 TE, 2 FLEX each week. Should I trade my freeman/coleman combo and ty Hilton for Melvin Gordon and Michael Thomas? I’m playing a team that’s sold for picks next week so I can comfortably eat Gordon’s bye. My skill position current roster is:
QB: Dak, Stafford
RB: Shady, Freeman, coleman, Tolbert
WR: Crabtree, fitz, Hilton
TE: Walker, Jonnu Smith

Might spend a top waiver on Alex Collins or Robbie Anderson for some depth this week, opinions on the trade?

Thought just occurred, what about maybe moving fitz on chance Hilton gets dealt before deadline
