STACKED’s take

Negative signalBust

Poor projection with 13% ownership created worst-case DFS scenario.

Jameson Williams was the worst type of DFS play in Week 3: 'slappy chalk' with poor projection and high ownership (13%). Davis Mattek stated 'when Jameson Williams projects not good, which he definitely did not project good, and he is 13% owned, that is as bad as it gets.' Pre-lock ownership was significantly lower at 6.3–10%, suggesting a late-week ownership spike. Despite the poor projection, Williams played in a winning lineup. Mattek later expressed regret about the selection, saying 'I didn't like Jameson at ownership, either. So, I probably yeah, if I could have those two pieces back and do something different, I wish I would have.'
