"He's got a great demeanor about himself. He's one of those guys that you can just label 'professional.' He comes here every single day trying to get better," Kelly said. "Nate's not a guy who has bad days. Sometimes you see a guy walking down the hall and all of a sudden his shoulders are slumping, something is bothering him, or whatever - Nate's not that type of guy. He's come in here every single day with the mindset he's going to get better, and I've seen that from him. He's striving to constantly improve."
