If they don't get AJ Brown, and Diggs is unsigned, I'd just bring back Diggs on another 1-year deal. If you add Doubs to last year's WR room (or AJ Brown + Doubs with Diggs leaving) that's actually huge. But it can't just be Doubs.
Also it hit me, Tyreek Hill is still unsigned. That's interesting. A Chiefs reunion feels obvious but surprised it hasn't happened yet.
