Burn #1 Waiver for Mack (PPR)

Who should I drop!? Leaning Fuller to add some extra RB depth especially with michel injury.

QB - J Winston
RB - D Johnson
RB - K Johnson
WR - AJ Green
WR - C Kupp
TE - Uzomah
Flex - J Gordon
D - Rams
K - Zuerlin

B - D Baldwin
B - A Collins
B - S Michel
B - K Golladay
B - W Fuller

I would drop either Fuller or Collins.
