Before the start of FA, we heard tons of story's about how the Cowboys were primed and ready for the start of FA, then they sign two average players and go on vacation for a week.
I think that you've hit on something here and have thought it most of the day. The extension of the CBA pushed into their vacation time and they weren't prepared for it.
It was part of the conspiracy that Danny, Tags and Upshaw have to keep the Cowboys down. I just report. You decide.
