Florida sophomore cornerback Vernon Hargreaves III's first collegiate interception felt easy from the start.

The Gators were in man coverage against Toledo last season and Hargreaves, in his first game no less, was playing press. Hargreaves was already close to receiver Alonzo Russell, so once his opponent started going into a post route, Hargreaves already had it in his mind that he was going to undercut his man and the route.

Quarterback Terrance Owens was finished before he even released the ball. Hargreaves jumped the route, making a controlled guess that sealed Owens' fate.

"As soon as I undercut it, the quarterback threw it to me," Hargreaves said.

It was the first of a handful of outstanding plays he would make in his debut season. Hargreaves, who led the Gators with three interceptions and 14 passes defended, earned All-American honors and entered the 2014 season labeled by many as the nation's best cornerback.

Through two games, the 5-foot-11, 195-pound phenom already leads the SEC with five passes defended.

His speed, instincts, vision and natural playing ability make him a feared cover man and ball hawk. Equipped with more experience and skills, Hargreaves could be even better this season. After two solid performances, he will get his greatest test to date on Saturday in Tuscaloosa: Alabama wide receiver Amari Cooper.

"We knew this was coming," Hargreaves said of covering Cooper, who leads the nation with 33 receptions and is third overall with 454 yards. "He's excited. I'm excited. We both know the magnitude of the game and it's going to be a great matchup on Saturday.

"Everybody knows what's coming. Obviously I'm going to be covering him. I'm excited for it."

How exactly will he go about covering his toughest opponent yet? For Hargreaves, it's more instinctual than anything. He said he doesn't like to think too much on the field.

BEFORE THE SNAP

Hargreaves zeros in on opponents, trying quickly to recognize the offensive personnel. He counts the number of receivers, then shifts his focus back to the defensive call.

He concentrates on what his defense is doing, what the play is and what the calls are. Once the assignment is clear, his eyes move back to the receivers.

"Most teams nowadays don't really huddle, so you can't really get a lot of indicators when they break out of the huddle," Hargreaves said. "Really for me, it's the receivers."

Once the offense lines up, Hargreaves figures out his leverage. A receiver lining up really wide forces him to play with inside leverage. An inside receiver means outside leverage.

He plants his feet, balls firm, yet light enough for him to explode out of his stance and glide along the field. His hips are loose, making turning smooth in case the receiver pulls a move.

AFTER THE SNAP

"I understand what [receivers] might do and what they like to do, but other than that, I'm not out there trying to guess routes," Hargreaves said. "It's just all instincts . . . You can't really play off what they might do. You react to what they do do."

His feet are as quick -- if not quicker -- than most of the receivers he covers. His hands snap into position and his arms push as fast as his legs churn, pulling him stride-for-stride with his opponent.

"He's very instinctive, he's fast, quick," Alabama coach Nick Saban said Monday. "But I think probably his greatest asset besides having great ability is he's a very instinctive player."

BALL IN FLIGHT

What's impressive -- and for opponents quite frustrating -- is how Hargreaves plays with his back turned. He relies on his technique and trusts his instincts. If a receiver gets behind him, Hargreaves stays patient. He doesn't panic because he knows he has time.

Hargreaves' eyes shift to the receiver's eyes, which are planted on the ball. Once their hands go up, the ball is close, meaning it's time for Hargreaves to pounce.

"It's something you can work on, you certainly can enhance, but the guy really has a lot of poise with his back to the football," Florida coach Will Muschamp said.

Hargreaves is still young and learning. His brain is still dissecting new information about players and formations each time he sits down for his film sessions during the week.

"Most of my decisions are calculated," Hargreaves said. "I understand the situation, I understand what's going on in the game."

He'll have to be as calculated as ever against the nation's best Saturday.
