Those two guys - Jodie Meeks and Patrick Patterson - have indeed carried the load for the Wildcats this season, but Horn has been impressed with the rest of Kentucky's cast.
"I think what's impressive to me about Kentucky is their team and the way that they play - their depth, their length and their athleticism," Horn said. "It's going to be a challenge for us to go in there and play against a team like that.
"We're excited about the challenge and we need to find a way at some point to take another step and get a victory on the road."
Horn said his team's biggest issue is overcoming slow starts and opening road encounters with more firepower.
"I just think we've got to put ourselves in position to be able to win the game and that's something that we've not done in our two road games," he said. "We've gotten off to bad starts and we've dug ourselves into holes and we've not been able to get out of them. I think as doing an important facet of the game better or an individual doing anything in particular, I just think as a team we've got to play better and we've got to give ourselves a chance to win on the road. It's hard to win on the road in college basketball in league play.
"If you don't put yourselves in position to have a chance - it makes it that much harder. I think that is the most important thing to us, rather than focusing on one particular thing."
Kentucky (16-5, 5-1) had a five-game winning streak snapped in an 85-80 loss at Ole Miss Tuesday and will try to regain its stature in the SEC East standings. Although the Wildcats are 8-2 at Rupp this season, Kentucky coach Billy Gillispie said the Gamecocks will present a challenge.
"I think it will be a very interesting matchup," he said. "They're playing great and Darrin has done a great job of coming in an instituting his plan and getting guys to do it immediately. It's a hard team to play against and they give you a lot of different looks defensively.
"They're of the hardest teams (in this league) to guard, because of their ability to spread you out and make shots."
The Gamecocks will be led by junior guard Devon Downey, the second leading scorer in the SEC. Downey is averaging 19.6 points per game. In addition four of the team's five starters average double figures.
"When your best players come to work every day and really care about doing the right things and getting better, it makes it a lot easier for everybody - coaches included," Horn said. "There's no doubt Devon is a big part of that. I think we've gotten it (leadership) from more than just him and that's one of the reasons we have found a way to get better and really that's our only goal is to continue to make progress as the season moves on."
Gillispie also has been impressed with Downey.
"He really knows how to play," the Kentucky coach said. "He can make hard shots, make layups and he can defend. He's very vocal and it looks like he's a leader on and off the court."
Kentucky - Ramon Harris, Michael Porter, Perry Stevenson, Jodie Meeks and Patrick Patterson.
