It gnawed at him that two Kentucky turnovers in the first quarter took away any chance the Wildcats had to pull an upset after the UK defense had held Florida on its first two possessions.
"We just can't keep making the same mistakes," said King, who had a game-high five catches for 50 yards and an acrobatic touchdown catch. "Those mistakes just kill us.
"We just can't keep letting it happen. We have struggled with that all year. We've got to be a first-half team. We can't keep getting behind. There's always the next game. We have to put this behind us and prepare for LSU, but this is no fun."
Kentucky lost three turnovers that led to easy Florida scores, and that was way too much for UK's offense to overcome.
"When we execute, we are a good offensive team. But we can't keep stopping ourselves," King said. "It's frustrating. I would not say we are losing confidence, but it does wear on your mentally after a while when you make the same mistakes.
"It's all mental. Three turnovers ... you can't do that if you expect to win. As an offense, we are slacking off and killing our defense." Then King's frustrations briefly boiled over more than any other player has shown during UK's rocky 2-2 start that also includes a loss to rival Louisville for the first time in five years.
"This is football. It's not something you cannot take seriously. It's not just something you do," he said. "It's got to be a priority for everybody. Some guys have it that way, some don't. Put all your effort into it or get the hell out of here. That's the attitude you have got to have. Honestly, you have to feel that way to play in the SEC."
King doesn't expect the team to lose its intensity even with road games coming up at LSU and South Carolina, two more highly ranked teams. "We are always going to come out and fight. Don't worry about that," he said. "We believe in ourselves. We just can't make mistakes that force us to play catch up so much. I'm not down on guys. I just want everybody to care as much as I?do because I know we are better than this."
