As frustrated as we all are regarding the lack of any supporting cast for Paige in Dallas, I think we might be a little off base with with regard to filling needs via next year's draft.
Before that occurs, virtually the entire league's established players will be up for grabs as so many contracts lapse after this season.
For me, (somehow) demonstrating a competent coaching staff and front office and (again, somehow) showing that Dallas can be an attractive destination for the right free agents is the first priority - then grabbing whoever is the right fit, at that time, in the draft.
