He’s taken part in just four practices at training camp, but in that short sliver of time, Chicago Bears quarterback Jay Cutler shows evidence he’s poised to take a major step in Year 2 of Marc Trestman’s offense.

“It’s obvious in practice that Jay is taking more and more control by the day,” offensive coordinator Aaron Kromer said. “Not that he didn’t before; he did. But with his comfort level with all the things we’re trying to get done, he’s able to solve some of his own problems on the field, even when he didn’t maybe have that answer taught to him yet. It’s really helped that Jay has studied really hard all offseason. He’s worked on technique. He’s been one of the hardest-working guys on the team this offseason.”

In other words, Cutler isn’t resting on what the offense accomplished in 2013.

You know the numbers. The Bears set records last season in net yardage (6,109 yards), passing yards (4,281), completion percentage (64.4), passing touchdowns (32) and passer rating (96.9) in addition to achieving a franchise-best 344 first downs while scoring the second-most points in franchise history (445).

Cutler’s 63.1 completion percentage ranked second in franchise history, as he churned out a career-best passer rating of 89.2.

Cutler has long held a reputation for surliness, and the outside perception is he’s aloof with teammates. Yet within the organization, the quarterback didn’t display such qualities, according to the coaches. Actually, he’s quite the opposite, they say.
