ESPN's Josina Anderson tweeted the following Tuesday night, hours after news broke of the Buffalo Bills' trade with the Philadelphia Eagles:

A source close to LeSean McCoy to me on how the #Eagles RB feels about news of an agreement to trade McCoy to Buffalo: "He’s a Pennsylvania kid. He’s never played football outside of Pennsylvania—high school, college, pro. So of course he's not happy. Sounds like it’s pretty final to me unless LeSean is refusing to go to Buffalo."

On whether the source believes McCoy will make a trade to Buffalo difficult, in light of McCoy’s initial reaction to the news:

"It'll be interesting to see how this process plays itself out because he's an interesting individual. In your mind, when you think of Buffalo you think of cold and losing games. It’s not like it’s the Philadelphia market where you’re always on t.v. and you’re playing for like the division title or that type of thing…It was unexpected. I'll tell you that much.”

The source on how McCoy is feeling at the moment:

"Honestly, he's frustrated ... It's alright. It's the league. I told him that. I guess he just never experienced that, but he was like 'why me.'"

The source said he thinks McCoy is "not going to make it easy, that's for sure."

The source on whether the trade news was a surprise:

"Honestly we were under the impression the whole time, that eventually at some point, Chip [Kelly] was going to ask LeSean to restructure his contract--not a pay cut, but convert some of his signing bonus."
