General manager Ryan Poles spoke with Jeff Joniak Sunday on the Bears pregame radio show on ESPN 1000 AM and 100.3 HD2 FM.

After backup quarterback Tyson Bagent made his first NFL start and helped the Bears to a 30-12 win last Sunday, Poles said "no one is really surprised here in the facility" by the rookie's success. Dating back to OTAs and training camp, Poles saw Bagent's poise and preparedness, which showed up against the Raiders.

"That work ethic has been incredible," Poles said. "There's been many times I've seen him on days off at the practice field taking extra reps and preparing just for if he had an opportunity. That seems to have paid off in the first game and we're excited to see him play today."

Poles was also complimentary of rookie cornerback Tyrique Stevenson after the Miami product had a career-high three pass breakups against Las Vegas. Acknowledging how difficult the cornerback position is now in the NFL, Poles was happy with Stevenson's game, which included helping limit All-Pro receiver Davante Adams' production.

"The one thing we knew from Tyrique was his level of poise when the ball is in the air but also his short memory," Poles said. "He can have a bad play or a completion gets caught on him, but his ability to erase that [and] go to the next one is incredible.

"A lot of times with these rookie corners, you gotta weather the storm and live with the ups and downs. I know he's gonna build off of this. He'll be callused by the end of the season and I'm expecting him to have a good career in the NFL."
