Flex spot

[QStar]

12 team 0.5ppr - starting 1QB, 2RB, 3WR, 1TE, 1flex(RB/WR/TE), 1 Offensive Player (QB/RB/WR/TE), D/st, K

Who would be a better flex starter? R.Mathews or M.Wallace? I feel like Wallace's wk1 stinker was more a function of J.Haden and Mathews had a pretty bad day if you take away the first receiving TD of his career.

The rest of my team:
QB - Newton
RB - A.Peterson, R.Bush
WR - M.Austin, J.Edelman, M.Williams
TE - J.Cameron
OP - A.Smith
Flex - R.Mathews/M.Wallace??
D/ST - CIN
K - Zuerlein
Bench - A.Dalton, B.Tate, B.Brown, G.Bernard

I like Wallace here. No reason to play Mathews after Battle was in for more snaps than him last week. Which btw......WTF
