When I got to Round 6 in my draft, I couldn't pass up the value of Darren Waller relative to the players on the board at that time. Players drafted after I took Waller are: Kittle, Lamar Jackson, CEH, Devin Singletary, TJ Hockenson, Trey Lance, Schultz, Mooney, Godwin.

Did I make the right call? Am I starting Andrews and Waller in my Flex?

QB: Kyler Murray
RB: Dalvin Cook
RB: Saquon Barkley
WR: Tee Higgins (10th round keeper)
WR: Courtland Sutton
WR: Allen Robinson
TE: Mark Andrews
TE: Darren Waller
Bench: Antonio Gibson
Bench: Darrell Henderson
Bench: Damien Harris
Bench: Chris Olave
Bench: Kedarious Toney

hard to say you made a mistake, your logic was understandable. Waller just concerns me due to his preseason injury. Also, with Davante Adams joining, i think some targets will be taken away from Waller.

With having Andrews, I think I would have looked elsewhere for a flex.

But Waller certainly does have the potential to outperform your bench.

It's actually a 2WR league so Allen Robinson would be my flex over Waller in that case.
