The Philadelphia Eagles sent shock waves through the NFL Tuesday when they reportedly agreed to trade running back LeSean McCoy to the Buffalo Bills in exchange for linebacker Kiko Alonso, via Adam Schefter of ESPN.

Apparently it shook up McCoy as well.

ESPN’s Josina Anderson reported that the explosive playmaker wasn’t particularly pleased with the news:

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.

The source also went on to tell Anderson that McCoy was “frustrated” and that he is “not going to make it easy, that's for sure" when discussing whether he will simply accept the trade to Buffalo or not.

McCoy’s numbers dipped in 2014 from his head-turning 2013 campaign, but he still ran for 1,319 yards and found the end zone five times. What’s more, he is only 26 years old and theoretically has a few productive years remaining on his odometer before reaching the magic age of 30 for running backs.

It seems like McCoy would have preferred to spend those years in Philadelphia.
