Five days after general manager Phil Emery endorsed the idea of Palmer serving as the Bears' primary backup to Jay Cutler in 2014, Trestman told reporters on Tuesday he sees similarities between Palmer and Josh McCown, who signed a two-year deal with the Buccaneers in free agency after throwing for 1,829 yards, 13 touchdowns and only one interception in place of an injured Cutler last season.
"I feel very good about Jordan," Trestman said. "I feel good about his preparation; his work ethic is very similar to Josh. He spends a lot of time here. He's taken over the tradition now of getting these new guys ready, the Josh Bellamys, the Josh Morgans, the Domenik Hixons, he's spending time with those guys during the off time to get those guys up to speed with the guys who have been around on the offense. He's taken on that role.
"He was very sufficient throwing the football last year in the preseason. We saw a glimpse of his ability to move a football team, and we'll see how it goes. Right at this point, you'd have to feel good about Jordan's experience. He doesn't have a lot of hits on him, right now. He's very much engaged in the offense."
Although Palmer, 29, entered the league in 2007, he's attempted just 15 regular-season passes over four appearances.
Trestman was asked if Palmer's limited body of work can be considered a red flag when evaluating whether a quarterback is prepared to be the No. 2 guy on the depth chart.
"I know he's been in the league for a long time, he's been around a lot of different offenses, he certainly looks like he can sufficiently throw the football the times we've seen him work, and he's a joy to work with every day and to help develop," Trestman said. "We all know that every quarterback's journey is different; sometimes quarterbacks excel at different times in their lives. We saw that with Josh. Steve Young didn't start until he was 29 or 30 years old. Other guys don't get it going -- [Rich] Gannon didn't get it really going until he hit the 30 mark, so there's no reason why Jordan can't continue to develop and be that guy."
