“He literally learned the offense on his own because we didn’t have time to work daily with him." Trestman told the Chicago Tribune. "He worked. He worked overtime and he learned the offense and came in and played admirably in the preseason. He moved the football team and was very sufficient.
“He’s got a lot of experience and not a lot of wear and tear. He’s been around a long time. Obviously, we’re going to have another one in there and see how that goes over the next couple of months.”
General manager Phil Emery expects to sign a free agent to compete with Palmer for the backup job.
Collins, 26, played in five games for the Bears last season, credited by team stats with 13 tackles and a sack before suffering a season-ending ACL tear in a Week 5 home loss to the Saints.
Palmer spent training camp with the Bears in 2013, was released before the start of the regular season but then rejoined the club in late-October after starting quarterback Jay Cutler tore a groin muscle. Palmer remained on the roster through season’s end but did not see action in any of the team’s final nine games.
He could be No. 2 behind Cutler this season if Josh McCown leaves as a free agent.
