Made Free Agency Moves, Drop Who For Defense Now?

10 team PPR redraft. My waivers just went through and I quickly dropped my defense (LAC) for the unclaimed Terry McLaurin, and as a Tyreek owner felt like it was the right move to act promptly and drop Justin Jackson to pick up Mecole Hardman. That being said, now I need to drop someone to pick up a defense. Should I drop Njoku? Or should I try a 2-1 trade? The trade option risks losing one of the better defense options by waiting. Looking at Buffalo Defense (vs. NYG) or Houston Defense (vs JAX)? Here’s my rest of the roster as of now:

QB: Patrick Mahomes
RB: Alvin Kamara
RB: Kerryon Johnson
WR: Chris Godwin
WR: Calvin Ridley
TE: Darren Waller
W/R/T: Miles Sanders
DEF: EMPTY will need to fill
K: Wil Lutz
BN: David Njoku
BN: Tyreek Hill (hurt)
BN: Dede Westbrook
BN: Lesean McCoy
BN: Royce Freeman
BN: Mecole Hardman
BN: Terry McLaurin
