You upgrade Thielen to Pittman and get Sutton as a flex. RB room is rough though. Gotta weigh whether the Thielen upgrade to Pittman and Sutton at flex is worth the downgrade to Stevenson/Pollard at RB.
I think it’s worth it personally. I feel like you can find fill in RB’s if need be. RB get hurt all the time. It’s a risk though.
