Drop one for Mattison?

Mattison is still a FA in my league, considering dropping somebody but not sure I need to do it. Opinions? roster below.

Roster Lineup: QB, RB, 2WR, 2Flex, TE, K, DEF

QB: Stafford, Burrow
RB: Henry, Mixon, Carson, Taylor
WR: Thielen, R. Woods, Campbell, Gallup, Ruggs, Sutton, D. Johnson
TE: J. Smith

I’d probably drop Burrow
