Gregory is not coming back to Dallas, even if Dallas wanted him back. He made that pretty clear on Twitter/X. He seems to think the Cowboys fans who supported him through all his suspensions are "toxic".
I still don't believe he wants to play anyway. He is getting $14 million from Denver so he can stay in Colorado or move to California and smoke all the weed he can buy with $14 million. Maybe he signs somewhere next year.
If Gregory had the desire and pride of Micah Parsons he could have been great. But like David Irving, he has other priorities. Both wasted a lot of God given talent. Jerry Jones gave him more than enough chances to play football, but in the end, after all Jerry did for him, Randy Gregory just stabbed Jerry in the back and laughed at him.
