"I think they have been progressing pretty good. We need more from them, but I?think I have seen a big improvement since we have started. But we have to have more. They have to push themselves and I?keep pushing them," Smith said.
He says Williamson is the one backup who has made the most improvement, but he likes what he's seeing from Miles Simpson, Malcolm McDuffen and Tyler Brause.
Junior starter Ridge Wilson, expected to be a more dominant player in UK's new defensive scheme, "He has done a good job. He is just a kind of guy that you have to stay on and you have to keep his attention. But he has all the talent in the world," Smith said.
"The good thing is that Danny Trevathan and Ronnie Sneed and Winston Guy have done a great job of leadership. They are our three seniors and have brought the linebacking corps and the whole defense together. We've still got to have more, but they have done a good job to this point and that rubs off on everybody."
