What would you do if you had invested a 1st round pick for someone who has yet to prove himself, at least somewhat due to injury? Regardless of what the popular opinion of Charlton is, or may be, the Dallas FO isn't likely to accept little or nothing for one who might ultimately prove himself to be worth more than what most teams would be willing to offer. Taco will probably remain a Dallas DE until this season proves him, without a doubt, drastically undesirable. I think this season will be his make-it or break-it last chance to prove himself worthy of keeping, barring being traded or cut.
