I'd argue Dunkley won't be any cheaper this season if fit. He's the 2nd most owned player and highest premium owned player in the league, he's a C/VC option, he's in a team that is a real flag contender, he'll be getting season high CBA numbers - I just think there's so many reasons to start him but very few if any to not start him.
But if he fires exactly as he should, anyone not taking him is putting themselves behind the 8-ball against effectively the entire competition. It's riskier not to own him than it is to own him. Because if he works out, you now have yourself a negative POD against 70% of teams and probably closer to 99% of relevant teams.
