BOURBONNAIS, Ill. -- Now that Bourbonnais is in the rear-view mirror, here are five things we learned in the Chicago Bears' two weeks at camp:

1. Cutler’s condition: Jay Cutler appears to be in the best shape of his career. It is well known that the 33-year-old quarterback changed his diet several years ago, but Cutler’s upper body appears stronger than in previous seasons. And there has been no dip in arm velocity; Cutler still throws the football with the same zip he had five years ago. Now, can Cutler limit the turnovers and flourish without playcaller Adam Gase? That remains a mystery. But from a physical standpoint, Cutler’s 2016 stay in Bourbonnais may have been his finest ever.

2. Rookie year reboot: Kevin White failed to practice (coaches’ decision) only one day in Bourbonnais, which is a stark contrast to last season, when the receiver sat out the entire year with a stress fracture in his shin. White’s ability to finish camp uninjured is a huge confidence-builder. And he routinely caught the football in practice. White still needs to perform in preseason games and then prove he can produce in the regular season, but so far, so good. There have been no serious setbacks for the former seventh overall pick out of West Virginia.

3. Mash unit: Unfortunately, White’s good health did not extend to the rest of the team. The Bears suffered a lot of injuries in Bourbonnais -- and to key players: Alshon Jeffery, Eddie Royal, Zach Miller and Hroniss Grasu. Football and injuries go hand in hand, but the Bears are banged up beyond belief at receiver and tight end. And Grasu’s torn ACL further depletes the offensive line depth following the unexpected offseason retirements of Manny Ramirez and Nate Chandler. The Bears’ roster is thin to begin with; Chicago can’t afford much more bad news on the health front.

4. Chill out: John Fox and Cutler finally spoke out about the ridiculous number of training camp fights, most of them involving veteran offensive lineman Ted Larsen. Players fight in camp -- that happens every year. But some of the Bears’ brawls went way overboard. You can’t have players running in from the sidelines or sprinting 50-plus yards to dive-bomb a pile. The team is lucky no one got seriously hurt. Cutler put it best when he said there is a fine line between being an aggressive team and a dumb team. At times in Bourbonnais, the Bears acted like a very dumb team. Thankfully, Fox put an end to it.

5. Rookie class: The top portion of the rookie class is quietly making a strong push to earn playing time. Second-round pick Cody Whitehair is the starting left guard until further notice, and Leonard Floyd and Jonathan Bullard have also made favorable impressions with the coaching staff. At the very least, Floyd and Bullard will be in the game-day rotations at their respective positions in Week 1. And Whitehair looks like a long-term solution in the interior of the line. Meanwhile, seventh-round choice Daniel Braverman received an extended look -- thanks to injuries -- at receiver, where he made a couple memorable grabs. The rookies still have a lot to prove, but none fell flat on his face in Bourbonnais. You couldn’t always say that with past Bears draft classes.
