FA just started and there's still the draft.
No way no how is Hardy playing for the Cowboys. If you do a little research it's sounding like Hardy is in strong company with Ray Rice. In other words, no team wants to touch him.
Do some research and you'll see that there are very few options in FA and the draft to fix the pass rush. That's my point. They wouldn't touch Williams at DE and he signed a reasonable contract. They probably won't touch Ayers as he'll get more then Clayborn did (who the Cowboys also apparenlty weren't willing to pay).
The draft? There are mixed reviews on Bosa being a real pass rusher terror or more of a good strong side end. Spence is probably the other option but he's a big character issue. What's left in the draft is just guessing after that for pass rushers.
So it seems our strategy for fixing one of our owner's claimed biggest needs is cross our fingers and hope we get lucky signing some bargain bin DE turns into a 10 sack guy or some rookie taken in the 3rd round develops immediately into a total stud pass rusher.
PS - Thornton would be a decent pick up. But he's a run stuffer more likely to help at the 1 tech. He's in no way a solution to our pass rush problem.
