PHILADELPHIA (973espn.com) — With free agency looming on Wednesday, a cautionary tale was developing in South Philadelphia.

The Eagles are reportedly in significant trade discussions with the Miami Dolphins revolving around high-priced cornerback Byron Maxwell, according to Ian Rapoport of NFL Media.

Rapoport described the potential deal as as "in the works."

Maxwell, of course, signed a six-year, $63 million deal with the Eagles last year in free agency.

The potential of moving the veteran would help Philadelphia with its salary-cap situation for the 2016 season. He is set to count $9.7 million against the cap and the Eagles  would save $4.9M of that with a trade with the rest serving as dead money.

Maxwell excelled a zone corner in Seattle, first as a nickel back and then a starter in 2014, but struggled mightily in his first season in Philadelphia while playing in Billy Davis' scheme, which required a lot more man coverage.

Of the 111 corners rated by ProFootballFocus.com last season, Maxwell finished at No. 75, hardly indicative as a top-tier, No. 1 option as his salary may indicate.

Overall Maxwell play in 14 of 16 games (all starts) and in 75 percent of the Eagles' defensive snaps (911) last season. He finished with a career-high 51 tackles with two interceptions and a fumble recovery.

The potential move could also signal that the Eagles will try to bring back pending free-agent cornerback Nolan Carroll, who had a solid season in 2015 before going down with a broken ankle in Thanksgiving Day.

Cornerback would also be put in play at No. 13 overall in the upcoming draft with Clemson star Mackensie Alexander and Florida State standout Vernon Hargreaves entering the conversation as potential options.

Meanwhile, in an example of just how dysfunctional Roseman and Chip Kelly's relationship was last year, Rapoport also reports that not only is DeMarco Murray on the trading block but so is fellow running back Ryan Mathews.

Most believe one of Kelly’s biggest mistakes during his lone year as the leader of the Eagles’ football operations was his overreach at the running back position.

As most of the league has continued to devalue the position from a financial perspective, Kelly replaced LeSean McCoy’s untenable cap number with big-money deals handed out to Murray and Mathews.

Murray signed a five-year deal worth $40 million before last season and Mathews inked a three-year deal worth $11 million with Kelly claiming their downhill styles were a better fit for what he wanted to do than McCoy.

The results proved anything but and the new regime wants to undo the sins of Kelly.

Murray, 28, still has four years left on his deal, which includes a $7 million base salary for 2016 and $9 million in guarantees. If he’s released prior to June 1, the Eagles would incur $13 million in dead money.

Mathews has a far more manageable $4 million cap number for 2016 so the issues with him likely relate to his inability to stay on the field consistently.
