Championship Roster Help!

Im in a .5 pt ppr and as of right now my roster is as follows:

QB: Lamar
RB1: Lev Bell
RB2: Mike Boone
WR1: Devante Adams
WR2: AJ Brown
TE: Hunter Henry
Flex: Robert Woods
Flex: Breshad Perriman

I have David Montgomery, Anthony Miller and Greg Ward Jr on my bench. Should I leave my roster as is? This obviously all depends on whether or not Mattison is playing for Minny. If he is, i’d probably have to slot Montgomery in.

What do you guys think?
