TRADE ADVICE: Kennan Allen for DJ and Locket?!

Hey guys in a 10 ten full ppr…as it stands my team is

QB: Tom brady
RB: Alex Collins
RB: Dion Lewis
WR: Michael Thomas
TE: Jimmy Graham
Flex: Kennan Allen

Bench: Mark Ingram, Sony Michel, Austin Eckeler, Sammy Watkins ETC.

Would it be worth it for me to upgrade at the RB spot but losing Allen who is obviously a ppr beast, also DJ worries me, thoughts??

Think I’d just keep what you have
