Jason Kelce contract could give hint of Alex Mack's worth

UPDATED: 12:30 p.m.

With one year left on his rookie contract, Philadelphia center Jason Kelce signed a six-year extension today.

Via Twitter, Adam Caplan reports the deal is worth $37.5 million, including $13 million guaranteed.

Does this set the market for Cleveland center Alex Mack? A little bit – I expect Mack to command more than that guaranteed figure.

Are the Jaguars willing to shell out that kind of money for Mack? Remains to be seen.

We’ll know soon after the March 11 open market signing period opens.

Mack, 28, remains the top center scheduled to hit the market, followed by Green Bay’s Evan Dietrich-Smith, Chicago’s Roberto Garza, San Francisco’s Jonathan Goodwin and New Orleans’ Brian De La Puente.

(UPDATE: Garza has reportedly re-signed with the Bears -- a one-year contract.)

All played more than 1,000 snaps for their teams in 2013.

The Jaguars figure to be in on Mack since their center spot is open after the retirement of Brad Meester.

What the Jaguars face: Do they allocate Offensive Line Free Agent Money on a top-flight guard early in free agency? My prediction is that they will.

But it would also behoove the Jaguars to at least reach out to Mack.
