Adam Caplan: Yes, the chances are strong that they will release him if they can't find a deal. Second-year WR Buster Davis is expected to handle the No. 3/slot role which has been Parker's for the past few seasons so that makes him expendable- especially at his salary.
Parker is set to make $1.85 million this season with a cap number of slightly over $2 million. That's a steep price to pay for a backup receiver. He also has three years left on his contract.
ML: The Chargers have several core players with two years or less left on their deals. Igor Olshansky is in the final year of his contract, while Philip Rivers, Shawne Merriman, Marcus McNeill, Luis Castillo, Chris Chambers and Vincent Jackson all have two years left. Which players on this list are the Chargers most likely to retain? Which of them are they most likely to lose? Are you hearing of any extensions that could be agreed to in the near future?
DE Igor Olshansky
Rivers, McNeill and Castillo are all priorities for the team to re-sign. They could choose to get one or two of them extended this season and, as you know, the team has been quite proactive in the past in getting their core of younger players signed early to extensions.
I'm not totally sold that Chambers will be back after his deal is completed. He'll have to show he can play at a high level for an entire season, same with Jackson.
As for Merriman, the chances are greater that he gets an extension but also keep in mind they're high on second-year OLB Jyles Tucker.
ML: Speaking of extensions, we've seen a couple of big ones this off-season with Ben Roethislberger and David Garrard. Will either of these deals help set the framework for Rivers' next contract?
AC: Probably so, considering Rivers has shown that he can win in the playoffs, although his regular season performance was inconsistent at best last season.
ML: The Chargers have three unsigned draft picks, including first-rounder Antoine Cason. Are you hearing anything that would lead you to believe Cason will not be in camp on time?
AC: His agents (Brad Leshnock and Rob Slavin) are solid in that they usually don't have holdouts, so I'd expect Cason to be signed on time for when the rookies have to report.
ML: San Diego seems pretty set with its roster as training camp approaches, but the team could still benefit from improved depth on the defensive line and at safety. Who are the free agents who could help the Chargers most in these two areas? Do you see the team making a move for any of these players?
AC: Veteran DE Rodney Bailey, who has played a lot in the 3-4, could help provide some depth.
No question that the safety position lacks depth at either spot. Veteran safeties like Mike Doss, Omar Stoutmire and Curome Cox could provide depth for their secondary.
