Part of having a roster made up of 64 percent underclassmen creates a consistent learning environment in the Nutter Training Facility. With Kentucky preparing for its regular-season finale at No. 23 Louisville at noon on Saturday, the Wildcats are getting a lesson in what the UK-UL in-state rivalry means to the Commonwealth and the fan bases from each school. The Wildcats have a total of 77 underclassmen on their 120-man roster and only 10 of the 58 players listed on the depth chart entering the finale at UL are from the Commonwealth of Kentucky.  “So excited about rivalry week, been educating the guys all week on the rivalry,” UK offensive coordinator Neal Brown said. “We educated them today about the Governor’s Cup, what it means. Some of the coaches talked about their personal memories. Some of the in-state guys are going to talk tomorrow. We’re just taking a little bit of our offensive meeting and trying to educate them, especially for some young guys from out of state, educating them, teaching them what a rivalry is and a little about Kentucky-Louisville.”Kentucky (5-6) enters the rivalry tilt with a lot more at stake than bragging rights. UK is seeking to earn its sixth win to clinch bowl eligibility for the first time since 2010. While any rivalry game brings the challenge of managing the added emotion, UK’s matchup in the Derby City will present a unique challenge for Brown’s offense. “Obviously Louisville is very, very talented on defense,” Brown said. “They’re well coached. They play hard. That’s the thing that struck me last year preparing for them — and I know it’s a different coaching staff, but it’s a lot of the same kids — they really get after it. They rise up every week. And they play good, solid defense, as good as anybody we’ve played.”The Wildcats will be seeking to reestablish an offense that shined early in the season in games with UT Martin, Florida, South Carolina and ULM, and 31-point performances in losses to No. 1 Mississippi State and Georgia over UK’s last four games. After UK had an eight-game stretch – including seven against SEC foes – the Wildcats benefited from a bye on Saturday, giving UK fresh legs entering the matchup at UL. “The bye was good for us. We needed it,” Brown said. “I think we were getting worn down there. We used last week to kind of re-engergize, coaches and players. We had a good, spirited workout today, do that tomorrow and then kind of wind down and get ready for Saturday at noon.”
