TE Upgrade Attempts

Looking to flip some of my depth into an upgrade at TE since that’s my weakest spot with only Tonyan. Was considering an offer for Pitts in full PPR

Tonyan + Damien Harris + Ridley for Pitts + Tyreek

Didn’t want both Ridley and Pitts so I’m also trying to move Ridley at the same time. Rest of my team:
QB: Brady, Lance
RB: Henry, Mixon, Edmonds, Ty’son Williams
WR: Ridley, Cooper, D Johnson, Woods, and AB

Tonyan is better than Pitts to start with, so I’m not quite sure of the point of this trade–just to make your team worse??
