"There's no fraud in Jason Garrett," he added, per TMZ Sports.
"Does he have some things he could do better? Of course," Jones continued. "But, what I think we have here is an asset that will get us to where we want to go, which is a championship."
Jones has long been publicly supportive of Garrett, though it's fair to question just how much his faith has been tested. The Cowboys are 2-3 to start the season and in Garrett's tenure have made the postseason just twice, winning only one playoff game in that time.
The Cowboys looked like a legitimate Super Bowl threat in 2016, finishing the regular season 13-3 behind a dominant run game, only to lose their first playoff game following a bye week before promptly underachieving in 2017, going 9-7.
The Cowboys now have a Super Bowl drought dating back to the 1995 season, and Jones wasn't always patient with his head coaches after the Jimmy Johnson and Barry Switzer eras, moving on from Chan Gailey after two seasons, Dave Campo after three, Bill Parcells after four and Wade Phillips after 3.5.
Garrett has been given a longer leash, however, despite reaching the postseason as many times as Gailey, Parcells and Phillips each did in shorter tenures.
And as B/R's Mike Freeman wrote, it's hard to pinpoint exactly what Garrett offers as a head coach:
"Does Garrett come up with brilliant offensive schemes like Andy Reid or Sean McVay? No.
"Is he a brilliant motivator like Bill Belichick? No.
"Does he inspire players? No. Does he intimidate other coaches the way Belichick does? No. Is he bold like Bears head coach Matt Nagy? Nope.
"Does he generate brilliant defensive schemes? No. Do his assistants? No."
Freeman added: "A number of anonymous coaching sources are ripping Garrett after the Houston Texans loss. He remains one of the few coaches who other coaches around the league routinely shred off the record. That's only gotten worse."
Freeman suggested that Garrett remains the head coach because he's willing to do Jones' bidding, that he's ostensibly a yes man. Perhaps that's the case. Perhaps there is a comfort to stability and longevity that has developed in Dallas.
What's harder to argue is that the results on the field completely justify Garrett's seemingly safe job status. If playoff appearances and postseason wins are the true marks of success, Garrett simply hasn't succeeded enough in Dallas.
