Could the team sign a free-agent guard or draft one, or perhaps two?

Could a right tackle be a possibility? That seems less likely with the presence of veteran right tackle Jermey Parnell, but a young player at the position could prove enticing.

On that front, Thursday at the combine – while a day of unknowns – is equally intriguing. There appears likely to be good offensive linemen available when the Jaguars select No. 29 overall in the upcoming draft, and No. 29 overall could be an ideal time to select one.

While left tackle often is a position NFL purists prefer in the Top 10, an interior lineman or a right tackle often seems a better fit late in the first round.

An early combine-week preview of the linemen here:

Notre Dame guard Quenton Nelson is the consensus best offensive lineman here, and is expected to go in the Top 10. That's rare for a guard, but he's considered a can't-miss player worthy of the selection.

"My mindset is being dominant," he told reporters Thursday.

After that?

Well, after that there's a lot of disagreement and a lot of thought that a lot of players could be available for the Jaguars at No. 29. Ohio State guard/center Billy Price has appeared in mock drafts at No. 29, as have Georgia guard Isaiah Wynn and UTEP guard Will Hernandez.

Wynn on Wednesday looked the part, and talked of his athleticism and of being able to play multiple positions. Nelson as expected looked the part, too, and said he believed it was right considering the quality of interior defensive players in the NFL that he be considered Top 5.

Tackle prospects such as Mike McGlinchey of Notre Dame, Orlando Brown of Oklahoma and Connor Williams of Texas also drew interest Thursday – and could draw interest from the Jaguars in April. They looked the part Thursday. They're intriguing.

Will they draw the interest of the Jaguars? Can they make the adjustment to the NFL?

That's a … well, tricky … question.
