One of the most underrated parts of the Philadelphia Eagles' success in the 2017 season is the job well done by general manager Howie Roseman. However, of all the deals he has successfully pulled off over the past few seasons that have helped the Eagles make an appearance in Super Bowl LII, Roseman is still haunted by the one he could not make.

Buffalo Bills running back LeSean McCoy was once one of the greatest running backs in Eagles history. Unfortunately, he became a casualty of the Chip Kelly debacle and was traded soon thereafter. According to Manish Mehta of the New York Daily News, Roseman attempted to bring McCoy back this offseason:

Kelly’s decision to trade McCoy to Buffalo for Alonso never made sense. Roseman tried to get McCoy back in a deal with Buffalo after Kelly was fired through back-channel intermediaries, according to sources. One of Philly’s off-the-books offers for McCoy, who has been a Pro Bowler in each of his three seasons with the Bills, was a package of players that included wide receiver Jordan Matthews, according to sources. Matthews ultimately was traded to the Bills (under a different regime) for cornerback Ronald Darby last summer.

However, his attempts were to no avail, as the Bills know full well the kind of playmaker they have in McCoy. As a result, Roseman still can't get over not getting back his star runner.

McCoy continues to be one of the best running backs in the NFL after nine seasons. He finished fourth in the league in rushing yards (1,138) and tied for first with runs over 20 yards (12). Needless to say, he would be a complete game-changer for Philadelphia this time around against the New England Patriots.
