Troy Aikman doesn’t understand why Mike McCarthy is no longer the head coach of the Dallas Cowboys.

The longtime Cowboys quarterback and Hall of Famer criticized the organization and owner Jerry Jones on ESPN Monday night ahead of the wild card matchup between the Minnesota Vikings and Los Angeles Rams. McCarthy and the Cowboys officially parted ways on Monday after negotiations between the two failed.

McCarthy will not return as the Cowboys’ coach next season, owner Jerry Jones announced Monday. He had been negotiating a new contract with McCarthy since his original five-year deal with the team expires on Tuesday, but the two sides apparently couldn’t agree on the length of a new deal. The move came about a week after the Cowboys rejected the Chicago Bears’ request to interview McCarthy for their head coaching position.

The Cowboys went just 7-10 that season and were one of the biggest disappointments in the entire league. They suffered several key losses, lost quarterback Dak Prescott to a season-ending injury, and missed the playoffs. The Cowboys still haven’t been back to the NFC Championship game since the 1995 season.

Aikman won three Super Bowls with the Cowboys, for whom he played from 1989 to 2000. He was subsequently inducted into the Pro Football Hall of Fame in 2006. Two of those Super Bowls that Aikman won came under head coach Jimmy Johnson. The third was in the 1995 season under Barry Switzer.

The Cowboys will now begin the search for McCarthy’s replacement, albeit a week late. While there are plenty of qualified candidates who could step in, Aikman doesn’t believe head coaching quality has been the real issue in Dallas over the past few decades.
