I'd be surprised, they've definitely got a filter set to require some kind of performance drop. Last year Petracca never got forward despite playing there more than any of the guys who actually did and the only reason I can see is because his scoring hadn't dropped (DT). Pretty sure they use it more as an "interest" mechanism so people with failed picks get a second chance but do everything possible to avoid changes that will fundamentally impact the integrity of the positions.
Basically if Gawn is forward enough to actually get FWD, you'll be getting bailed out of a bad starting pick anyway, at least assuming Grundy and any of the other rucks sustain premium levels!
I've also put Gawn into my side, I hate the pick but when the alternatives are a Darcy who has already had multiple issues and NicNat, well perhaps you just eat the 10-15ppg loss.
If only there was a Hickey type this year
