Micah Parsons' failed contract negotiations with the Dallas Cowboys were the talk of the offseason, and his falling out with owner Jerry Jones eventually led to a trade to the Green Bay Packers before the start of the season.The four-time Pro Bowl defensive end expected a lucrative extension from the Cowboys after they offered veteran quarterback Dak Prescott a four-year extension worth $240 million last September.However, the offer didn't reach the valuation Parsons expected and Jerry Jones explained the reason behind that with a jibe at the 26-year-old."It's very simple: Dak was indispensable in my mind," Jones said. "Micah wasn't. It's just numbers. It's that easy. And that's not personal at all."Parsons was at the AT&T Stadium on Sunday for the first time against his former team after his trade last month.It wasn't the first time Jones threw shade at the former Cowboys DE. The Cowboys owner pinpointed Parsons' weakness ahead of the Week 4 clash this week:“While he does make great plays, there is also a way to approach playing against Micah — as we know, because we didn’t exactly win the Super Bowl those years.”Micah Parsons shares heartwarming moment with "mentor" Dak Prescott on Dallas reunionAhead of the Week 4 clash, Micah Parsons showed respect for his former teammate, Dak Prescott, hailing him as a "mentor" and said it would be "panful" to sack him.“It’s going to be painful,” Parsons said. “That’s my guy. He was always like a good mentor for me. But you know how it is, he always told me if I ever faced him that it’ll be a great matchup, so I’m excited to see what Sunday brings itself.”Parsons did get a chance to sack Prescott and it came on a crucial play in overtime, stopping a potential TD from the veteran quarterback.Following the game, Parsons and Prescott shared a heartwarming moment on the field.“I'll always believe in you, boy,” Parsons said while hugging Prescott. “I'll see you soon.”While the Cowboys failed to win, Prescott completed 31 of his 40 attempts for 319 passing yards and three touchdowns on Sunday.
