On the radar: John Estes

A player, coach or issue that should be on your radar as training camp approaches.

Jacksonville needs better play from the center position, and undrafted rookie John Estes from Hawaii has a shot to make an impact in the middle of the Jaguars’ offensive line.

Brad Meester, 33, has battled a lot of injuries. But even when he was on the field last season, Meester’s run blocking was a problem. Replacing him makes a lot of sense, but at the minimum, Jacksonville needs to put pressure on its current starting center’s hold on the job.

If Meester is replaced, the most likely scenario would be for Uche Nwaneri to move from guard to the pivot. Considering the volatility of this offensive line last year, Nwaneri -- while far from spectacular -- should be considered rather dependable. Plus, Jacksonville did just trade for Justin Smiley, creating is a bit of a logjam at guard with Vince Manuwai and Kynan Forney. So moving Nwaneri seems like a logical move after the acquisition of Smiley.

But where does Estes fit in -- and, to a lesser extent, Cecil Newton, who is a year older than Estes? If Nwaneri can prove that he is the best option for the starting center spot, Meester could be shown the door, which would open up a possibility for one of these youngsters. Estes is the guy I would expect to take advantage of that opportunity.

Estes isn’t a particularly big offensive lineman and Jacksonville certainly does value size up front, but he moves well and is tough and durable while playing the game with a bit of a mean streak. He isn’t extremely powerful, but was a four-year starter, is very aware in protection and has a good feel for maximizing his leverage advantage. There are tons of examples of offensive linemen who enter the league and prove very difficult for their coaching staff to cut from the roster. Estes might just be next.
