In the world of free agency, chasing after a center doesn't exactly spring to mind as a bold, game-changing move.
Acquiring Cleveland Browns center Alex Mack, however, would be exactly that. The mammoth 6'4", 311-pound blocker has never missed a start in his five-year career, and Pro Football Focus (subscription required) ranked him as the league's fourth-best center last season.
The problem for teams looking for center help is that that Browns slapped Mack with the transition tag, meaning the team will have the option of matching any competing offer coming from another team.
Since Cleveland used the transition tag instead of the franchise tag, the Browns would receive no draft-pick compensation should another team find a way to sign Mack away. However, since the Browns are in line to pay Mack approximately $10 million this coming season under the tag, any competing offer would likely have to be a massive one.
Mack's agent, Marvin Demoff, told TheMMQB.com's Peter King that he doesn't believe the tag will ensure Mack remains a Brown and that he believes he can create a contract that the team won't offer.
So far, though, there have been no takers, and Mack's situation has pretty much been a non-story throughout the free-agency period.
There were early reports that the Indianapolis Colts and Baltimore Ravens had interest in trying to acquire Mack, per NFL.com's Ian Rapoport, but both teams are likely now out of the mix.
Baltimore recently traded for Tampa Bay Buccaneers center Jeremy Zuttah, and the Colts signed former Dallas Cowboys center Phil Costa.
As things currently stand, Mack appears likely to remain a Cleveland Brown for at least one more season.
