Here’s a look at some Bears Essentials, coming out of the club’s comeback victory over the Cincinnati Bengals:

- ESPNChicago’s Jon Greenberg takes a closer look at how the Bears produced their first win of the Marc Trestman era. In describing the coach, receiver Brandon Marshall said, “His hands stay steady. There's no ups and downs. He's special, man. It's too early to call this a special offense. But in that second half, you could see why the Bears hired Trestman and what he can do with this maligned unit. I saw the promise there and they did too.”

There’s no doubting that. With Trestman running the show, it appears the Bears will be just as aggressive with the play calling on offense as they’ve been on defense over the years. Conservatism appears to be a thing of the past with this offense, and that’s a good thing.

- Jeff Dickerson runs through five things we learned about the Bears from Sunday’s win over the Bengals. Anybody remember all the drama concerning Marshall’s hip? Here’s what Dickerson had to say:

“All the commotion about Marshall’s hip last week was overblown. Marshall doesn’t like to practice, but he loves to play in regular-season games. If that isn’t obvious by now, you haven’t been paying attention. The Pro Bowler appeared to be in mid-season form on Sunday, catching eight passes for 104 yards and one touchdown on a team-high 10 targets. Marshall needs the football. He’s great. He just doesn’t need to have the ball thrown his way when he’s double-and triple-covered.”

- Here’s a recap of how rookies Kyle Long and Jordan Mills performed in their first NFL starts.

- The Bears took advantage of rare man-to-man coverage on Marshall for his 19-yard touchdown in the fourth quarter.

- Trestman receives an A-minus on his NFL head-coaching debut, but receives a game ball from linebacker Lance Briggs.
