White for Tate?

Hello everybody,
need help, should I accept?
Someone offered a Trade to me after I löst K. Johnson last week.
My Golden Tate for his James White.
Full PPR, save in the Playoffs 14,15,16,17
My Team
Wentz, Tannehill
Bell, Chubb, Mixon, (Johnson)
Woods, Sutton, Jefferey, C. Samuel, AJ Green and Tate
Def and K are streamer

Playoffs matchups are juicy for both.
White: KC, Cin, Buf, Mia
Tate: Phi, Mia, Was, Phi

I need a RB but Tate seems to be my steal at WR with this match ups, or not?
Accept or reject?
