Can Bears, Cutler keep this up?

I was lucky enough to be on the radio call for ESPN on Sunday afternoon for the exciting Minnesota Vikings-Chicago Bears matchup and I came away very impressed with what I saw from Jay Cutler and this Chicago offense. On a rainy day (perfect weather for an NFC North showdown), Cutler and the Bears moved the ball very well throughout the first half and on a spectacular final drive against the Vikings.

Cutler, who is playing under his fourth offensive coordinator in five seasons, still showed a mix of good and bad, but he definitely looks more comfortable in this Marc Trestman-run offense.

What is Trestman doing differently this year calling plays for Cutler, and can Chicago's offense keep it up?

Let's examine why they've been so successful so far this season.

Variety of formations

The first thing that jumped out to me was the variety of formations the Bears are now able to employ. They went with "12" personnel (one running back, two wide receivers, two tight ends) a lot in this game, which forced Minnesota's hand on defense. Several times throughout the game, Chicago motioned the TE into the backfield to get another blocker for Matt Forte or flexed one or both out wide to get favorable matchups on the outside against linebackers or safeties.

One of the big reasons Chicago can be multiple in its formations is because of Martellus Bennett. The big free-agent acquisition is a matchup nightmare, especially in the red zone, and has terrific hands and body control. He had another outstanding game, with seven catches for 76 yards and two TDs.
