Chiefs running back Knile Davis is making a good impression on his coaches this offseason.

Running back coach Eric Bieniemy likes what he sees so far from Jamaal Charles' backup.

"First and foremost, Knile has taken a tremendous jump mentally," Bieniemy said. "The beauty of it is last year was his first time going through it. Now he's been through it. Now we're just rehearsing everything, and we're going over the things we made mistakes on. He has a better awareness of what's going on with the game. Obviously he comes out here every day and he works his tail off. The beauty of it is he's learning how to become a professional. He's gaining a better understanding of awareness, of what it takes to be a professional, what it takes to see a blitz coming, how to apply the proper technique when pressure is coming. So he's doing a great job so far."
