Bruce Arians felt betrayed by the Pittsburgh Steelers when they let him go after the 2011 season.
Arians was offensive coordinator from 2007 until 2011.
"I got a call on Monday and [Tomlin] said, 'I can't get you the money.' I said, 'OK,'" Arians said. "He said, 'No, I can't get you a contract.'
"I said, 'Are you firing me?' He said, 'No.' 'Well ... it's just a matter of words, Mike. OK. If I don't have a contract, I'm fired.'"
The Steelers made two Super Bowl appearances with Arians as offensive coordinator, winning the title in 2008. Explaining why he felt betrayed, Arians said it was because he felt he had "done a good job."
"Maybe not the right image, but it was a damn good job," he said. "I was pissed. But again, time heals things."
Arians moved onto the Indianapolis Colts before becoming head coach of the Arizona Cardinals in 2013.
