The Bears have been impressed with just about everything rookie running back David Montgomery does since drafting him in the third round — including his ability to learn well. Montgomery had a rude introduction to pass protection from Roquan Smith early in camp, but since has improved.

“He’s gotten better each day,” running backs coach Charles London said. “I told him, ‘Ro’s a pretty good rusher. That’s not the first time Ro’s beat a back there.’

“That was his first day. We studied it on film. We talked about ways to improve and it’s carrying over. I don’t think he got beat once [Monday]. I think [it] was one of his better days. He’s just that type of kid. We try to find something — ‘Let’s get better at this today’ — and he attacks it and goes for it.”
