Gillislee for Brady? General Gillislee trade value discussion

I have a guy in my 12 team standard league who is offering Tom Brady in exchange for Mike Gillislee. I followed the footballers late QB strategy and was burned by Dalton Wk1, but I was still planning on streaming QBs most week.

I am stacked on RB for now and want to sell Gillislee high, but I was unsure what to target generally. Who are Gillislee owners getting in return in their leagues?

QB: Carson Palmer
RB: Devonta Freeman, DeMarco Murray, Mike Gillislee, CJ Anderson, Doug Martin
WR: Michael Crabtree, Alshon Jeffrey, DeVante Parker, Martavis Bryant, Rishard Matthews, Tyrell Williams
