Sermon and Justin Jefferson for Cordarrelle Patterson and Ja’Marr Chase (these guys are mine). Full PPR, Patterson is set as RB and double TD points for out of position TDs (ie. 12 points for receiving TD by RB). I am currently starting Zeke and Gibson at RB (but would probably start Patterson in place of Gibson this week) and Ridley, Moore and Mike Williams at WR.
I wouldn’t trade Patterson for Sermon unless it was dynasty. Maybe not even then considering the “out of position TD” bonus. Since Jefferson and Chase are a nearly even swap, I would say keep your guys, or demand a LOT more!
