It seemed that the Eagles had a replacement plan in place after they traded all-pro running back LeSean McCoy when reports surfaced that former 49er Frank Gore would sign with the squad.

But shortly after that news broke, Gore changed his mind, deciding instead to sign with the Indianapolis Colts for ery similar money: a three-year deal, with $7.5 million guaranteed. Since the money was virtually the same, there had to be other factors that ultimately played into Gore's decision, right?

Well, according to a recent report from FOX Sports, there were doubts Gore had about the Eagles offense and the approach of their head coach.

From Fox Sports' Mike Garafolo:

Gore had significant concerns from a football standpoint, and one of them was whether the Eagles would struggle without Maclin and without a big-time receiving threat. Eagles coach Chip Kelly, who now has full control over personnel in Philly, clearly put a price on Maclin's services and wouldn't authorize the team to match a contract from Kansas City.”

The Eagles have lost three big-time playmakers in DeSean Jackson, LeSean McCoy, and Jeremy Maclin over the past 12 months. There are also uncertainties surrounding the quarterback spot in Philadelphia, while the Colts have one of the best young quarterbacks in the league in Andrew Luck.

Gore's concerns weren't limited to the Eagles' offensive arsenal, however, as sources said the running back was also wary of Chip Kelly. From Garafolo:

A source said Gore also indicated to a friend he was concerned with what he heard about [Chip] Kelly's overbearing approach in Philly. Kelly's intense, no-nonsense approach — which has helped make him successful throughout his college and professional coaching career — initially rubbed McCoy the wrong way, though McCoy and Kelly were able to patch up their relationship for a good part of their two seasons together. However, receiver DeSean Jackson and cornerback Cary Williams were among those who didn't mesh well with Kelly's philosophy, and Williams indicated Kelly's lengthy, up-tempo practices were an issue for veterans who wanted to rest their bodies during the week.”

Gore's decision leaves the Eagles still in need of a backfield complement for Darren Sproles and Chris Polk, while Kelly's moves have some questioning his motives.
