I'm fairly confident that the same staff that took so long to trust Williams' play will re-evaluate his contributions and either accept his contractual demands or allow him to seek greener pastures. I see the 2017 draft to be one that the staff will look upon as desirable to find help at WR.
Of course, whether this finds Williams remaining a Cowboy next year or not remains to be seen. He's capable but certainly not indispensable. Much depends upon the nature of the contractual numbers that Williams and his agent demand. For all concerned, it would best be reasonable.
