Dallas is a mess in several positions and has limited cap space. They can free up a bunch by messing with Dak's contracts (his cap hit is $89m) and cutting a few guys, but I don't think they can afford go RB in R1, much less give up any real draft capital to do so. They also only have 3 picks in the top 150 this year, hard to see them giving up one of those to come up given their huge OL and front 7 holes. Their starting 3T, DE, LT, RG , MIKE, SAM and several backup are FA. Wouldn't surprise me if they resigned Rico Dowdle, who shouldn't be too expensive especially with a 2 year deal.
