Dynasty Trade - Singletary for Chark?

Devin Singletary for D.J. Chark in dynasty? YAY or NAY?

For dynasty probably nay. Never played but feel rb value skyrockets over wr. There will be another chark that comes up next year but not sure how many new RBs will be relevant for next year. most teams seem pretty set on number one guys, most draft picks will fill backup rolls imo. Hou, Miami, atl or AZ looks to be the only ones that could take a high draft pick for a day one starter.

I’d keep Singletary in a dynasty.
