The LeSean McCoy trade to the Buffalo Bills came together very quickly. The trade was one of the biggest in the NFL in recent history.

The trade took just 30 minutes to complete after the Bills were "stunned" to learn that the Philadelphia Eagles were interested in trading McCoy.

"The trade for LeSean happened really quick," Ryan said at the NFL owners meetings. "We were all sitting there. We were having organizational meetings. ... And all of the sudden we get this call from Philadelphia and I think that was when the trade started. Probably 30 minutes later, the trade was done."

The Eagles called the Bills about McCoy being on the market, which surprised the Bills.

"We were just kind of, like, stunned there for a little bit," Ryan said. "We're like, 'Really? Wow.' All right, so let's just take it from there. Obviously we were interested and then the trade came down. We knew it wasn't going to be cheap by any stretch. And losing a player like Kiko Alonso is obviously a steep price, but we felt really good about it."
