While covering several topics related to next week’s NFL Draft, Jaguars general manager Dave Caldwell was asked which position was the toughest to analyze.

His answer was surprising because he didn’t say quarterback.

“The most difficult position to evaluate on tape is cornerback,” Caldwell said without hesitation. “It’s just a hard position to evaluate because of the college game and obviously our scheme will be a little different than what a lot of colleges play.”

What Caldwell, Bradley and the Jaguars’ defensive staff might do throughout the draft is continue rebuilding a secondary that has only one returning starter (safety Dwight Lowery) and almost no depth.

Currently under contract are three safeties and four cornerbacks.

While most mock drafts have connected the Jaguars with a defensive lineman, a bold move at No. 2 would be Alabama cornerback Dee Milliner. Bold because it would be unprecedented.

Since the AFL-NFL merger in 1970, no cornerback has been drafted in the top two. Only two have gone at No. 3 — Bruce Pickens to Atlanta in 1991 and Shawn Springs to Seattle in 1997.

It would be a surprise if the Jaguars go with Milliner because they have so many other needs, and Bradley said earlier this week he feels “pretty good” about the organizational plan at the position.

“There’s a lot of depth in the draft, it appears,” he said. “There are guys in a lot of rounds that have capability of playing, and we’re excited about that.”

A good bet, though, is they will have to rely on rookie cornerbacks at some point. And they’ll experience a transition.

“It takes a special skill set to play the position and a special mind-set to play it at this level, and it’s tough,” Caldwell said. “You’re out there on an island, play after play, and you need to have great mental toughness and great physical toughness.”

The type of cornerback Bradley likes to have on his defense was documented in Seattle: tall and physical.
