Calvin for Dez straight up. Who's getting the better end of that deal? 3-1 team has Calvin and thinks Dez will be more help come playoffs. 1-3 team has Dez and feels they need help right now....
If it's true Dez is on pace to return Week 7, I'd probably rather have Dez. Detroit O doesn't look good and they don't seem to throw deep to Calvin much. So longer term, I'd take Dez. I can see how both teams would feel the need to do the deal.
