Bears rookie guard Kyle Long knows what quarterback Jay Cutler looks like. How couldn’t he? But it was good to put a face to the name in person, he said — good to shake the hand of the guy he’s working his tail off to protect. ‘‘Jay came out here and we met and we walked through the hallways,’’ Long, the Bears’ first-round pick, said after rookie minicamp ended Sunday. ‘‘He seems like a really cool guy. He was just checking stuff out, and he just wanted to make sure we were learning and working.’’ Cutler visited Halas Hall this past weekend because he wanted to meet and welcome the rookies. Long, of course, figures to be one of the most important to the recently offensive-minded Bears, especially with the emphasis the team is putting on interior protection. ‘‘We hadn’t met before,’’ Long said. ‘‘We just had some text interaction. Getting an opportunity to shake his hand was a cool deal. I’m looking forward to protecting him.” But it will be the last time Cutler and Long talk in person for some time. While Cutler is coming in, with the Bears’ organized team activities beginning Monday, Long is heading out because of an NFL rule that prohibits him from taking part in OTAs until after his final exams at Oregon. In other words, the last three days at minicamp were invaluable for Long. Offensive coordinator Aaron Kromer used rookie camp to go over assignments, techniques and footwork with his offensive line. Long said there’s ‘‘a list of things’’ he needs to work on as he heads off on his own — he’ll just have to work on them in unconventional ways.
