can’t answer that cleanly as you haven’t given your team construction and is this redraft? The Frowns are a mess and I would not want anyone from that team as Watson is the cloud that keeps on giving. If the niners start out 2-0, I could see them putting him on IR for 4 weeks having him back for week 7 vs. the Chiefs. Mason’s value goes up if CMC goes on IR.
SOunds like a solid hold for the moment, maybe you get some more use outta him, maybe you get better value in a minute, who knows, CMC could come back, go down again, and you end up with league winning low end RB1 for free entry
