This is one of two or three positions I think the Titans could use their first pick on.
Alterraun Verner is entering free agency, and even if he could be retained, the Titans may elect not to keep him, since they appear to be trying to move toward a system that doesn't favor his skills.
If Verner is gone, then the Titans will need a rookie who's ready to start immediately, which almost necessitates a first-round pick.
Where the Titans are looking like they'll pick (I have them at 17th overall right now), there's a chance one of the first couple of corners will be available.
Among the top prospects that might be there are Ohio State's Bradley Roby, TCU's Jason Verrett and Florida's Marcus Roberson.
Roby entered the season as the top corner prospect, but off-the-field incidents that got him suspended for Ohio State's first game could push down his stock. Still, he's the kind of tall, fast, playmaking corner that can start right away.
Verrett is a corner very much in the mold of Verner. He's short, but quick, and he can read an offense. Through just three games, he has 15 tackles, two for a loss, a sack, and five defended passes. His only issue is the fact that he's not physically what the Titans are looking for across from Jason McCourty.
Roberson is tall and lean, and looks to be a good cover corner. He's extremely athletic, but needs to add some weight and may benefit from having another outstanding corner across from him.
What corner the Titans pursue would largely depend on where they are planning to go with their defensive scheme, but I like Verrett's ability to read an offense. If Verner couldn't be retained, he'd be my choice.
