Brian Billick, who went 80-64 and won a Super Bowl in his nine seasons, was fired Monday along with his staff after going 5-11 in 2007.
"I would definitely like to see Rex get his shot," defensive lineman Kelly Gregg said.
Ryan said he appreciated the players' support.
"I think they understand the kind of person I am, that there's accountability and there's discipline," Ryan said. "They know I'm a straight shooter. They know I care about them and respect them."
