It's impossible for D.J. Durkin to miss.
The Florida defensive coordinator sees it all over the Kentucky football game footage: "You can tell he's got his thumb print on the program."
It's the Stoops stamp. Durkin has seen it before and knows it on sight. He's known Mark Stoops for a long time; they've coached against each other. They're from the same hometown of Youngstown, Ohio.
So while Durkin has spent most of his free time studying the Cats' offense, he can't help but notice the defense.
Never miss a local story.
He sees a Stoops team.
"They're playing really hard," he said of Kentucky. "They're playing with belief and confidence. They're very disciplined in what they're doing. ... I totally see that he has instilled that in the program and has done a good job of that. We have a big challenge ahead of us."
It's something Florida's coaches have pointed out to their players in this week of game preparation. This isn't the same Kentucky from a season ago.
"These guys are playing very disciplined; they're playing with great technique," Durkin said. "They're playing with great confidence. You can tell the other team has belief in what they're doing. Our guys know that. They recognize that."
