First time doing auction. 12 team 1 PPR. 6 pt QB TD. 1QB2RB2WR1TE1Flex. Everyone waaay overpaying for RB1s and I started feeling crappy around the 30th pick. But I got A rod and R Gronk cheapish because of it. My roster…
QB: Aaron Rodgers
RB: Alex Collins, Jay Ajayi, Rex Burkhead, Tevin Coleman, Jamal Williams, Kerryon Johnson.
WR: S. Diggs, D. Thomas, G. Tate, C. Davis, M. Goodwin, R. Cobb
