Jimmy Clausen, who was drafted by Carolina in 2010, will back up Bears' starting QB Jay Cutler.
"They both competed really hard for the job," Trestman said. "As I told Jordan, Jimmy played at a consistent level, as did Jordan. I really threw out the five or six plays Jordan had the other night backed up. I know Jordan was terribly upset about that situation. That really didn't come into the consideration. Jimmy's played a lot more football in this league. He's younger, and I thought the competition was very close. But I thought at the end of the day, I think the upside for Jimmy, his age, his experience, and he came highly recommended from some people I trust in Carolina."
Clausen and Palmer put up similar numbers through the first three games of the preseason. Palmer completed 70 percent of his passes for 225 yards, a touchdown and an interception for a passer rating of 88.9. Clausen hit on 64.9 percent of his throws for 280 yards, two touchdowns, an INT and a passer rating of 94.4.
But Clausen has started in 10 of the 13 regular season games he's played in the NFL, while Palmer has thrown just 15 passes in the four games he's played. Clausen is 26. Palmer is 30.
In what proved to be the final test pitting Clausen against Palmer on Friday night in Seattle, neither produced stellar numbers. Palmer completed 7 of 10 for 48 yards to finish with a passer rating of 80.4. Clausen hit on 6 of 9 for 36 yards and a 74.3 passer rating.
"It's good that the coaches have the confidence in me to name me the No. 2 behind Jay [Cutler]," Clausen said. "But we've got a long way to go. I don't even remember the last game I played, my rookie year. But it's a great opportunity like I said from Day 1. [I've] just got to keep going out each and every day, getting better and doing everything I can to help the team win."
Clausen put together a solid workout in June at Halas Hall, in addition to a reassuring personal interview and X's and O's session on the board, prompting the Bears to add him to the mix in their search for a primary backup to Cutler.
The team liked Clausen's experience, mechanics and football smarts, as well as his mental toughness. In addition to handling injuries and a lack of success as a rookie, Clausen quietly weathered the disappointment of the Carolina Panthers drafting Cam Newton and immediately inserting him as the starter.
"His ability to handle the adversity that he had in his first year, his leadership qualities, he stood up tall through a lot of tough times in Carolina, and gained the respect of his teammates and the team there with the way he handled himself in a very, very difficult year," Trestman said. "So that, plus performance, plus experience, plus youth were a lot of the reasons if I can give you some content. It wasn't everything. At the end of the day it really comes down to how you feel about things. You weigh some content there that I gave you to make that decision. We wish Jordan the best. He not only competed hard, he really invested in our football team. He emotionally invested. He coached. He shared. He coached other guys up, guys at his position. He's a tremendous young man, and we'll look forward to him landing on his feet somewhere."
Palmer expressed gratitude for the opportunity in Chicago on Twitter on Sunday, posting "I'll be wearing #Bears gear and supporting the Bears for the rest of my life. Regardless of what happens. This is the best org in the NFL."
Clausen, meanwhile, believes his experiences in Carolina -- while negative -- might have helped with the latest situation.
"One of the big things is sitting and looking back on the sidelines the past few years in Carolina just sitting and learning really did help," Clausen said. "I didn't have that in college. I didn't have that in high school. Just to sit back and take a step back and look at everything helped the game slow down a little bit for me, and [I] just learned how to play in the NFL because it's totally different from college."
