This is key too,
"Kingsbury has been labeled a players' coach over the years by many on his staff and in the locker room. He's well liked and has support among his players. Conversely, Kingsbury's aversion to confrontation chafed some players at times.
As one longtime ex-Cardinals player said, Kingsbury's go-to line in meetings, especially after bad performances, was that "everybody has to play better." While that approach fosters good relations, the player said, calling out bad performances by name can be necessary at times.
"It's a very comfortable work environment, but he won't rip anybody, and if the head coach won't do it, it's hard for the offensive guard to do it," the player said. "I think that's some of what's gone on with the QB." A team source added that Kingsbury's personality doesn't lend to calling players out."
