LAKE FOREST, Ill. — As if Ka’Deem Carey needed a reminder that he was no longer in the desert, it hit him in fluffy flurries this morning.

“I don’t think he ever saw snow before,” joked his Bears roommate, former Heisman Trophy finalist Jordan Lynch, a Chicago native. “He had two sweatshirts on coming out, and it wasn’t that bad.”

When the two-time Arizona Wildcats All-American arrived for the first day of the Bears’ rookie mini-camp, he was thrilled to see they were practicing in the Walter Payton Center, the team’s indoor facility.

“Yes, we’re not outside in that cold,” the running back said. “So I can do a good job and show off for the coaches. …

“I was dummy-shocked, man.

“Ain’t nobody told me it was going to be snowing out there.”

Once Carey got indoors, he shined. In the team’s offensive drills, the favorite to win the Bears’ backup job behind Matt Forte showed the electric style that belied his 4.7-second 40-yard dash time at the NFL Scouting Combine.

“I also think track speed is different than football speed,” he said. “You get on the football field. You have a lot of quickness, you have a lot of moves. You have to get away from people.”

Carey hoped he brought a “lot of energy” to the team’s mini-camp, which ran about 1 hour and 45 minutes today and continues for the next two days.
