“Chip is ... he wants to win,” McCoy said. “He’s very, very intelligent. The offense, they’ll find ways to get big numbers. They’ll find ways to put stats up offensively. You just got to, I think, with him coming in there, no matter how good of a player or lower of a player you are, if you just automatically believe him - no matter if it sounds crazy and you’re like, ‘What is he talking about?’ - if you just automatically believe and buy in, I think you’ll be fine.”
Kelly traded McCoy to Buffalo in March in exchange for linebacker Kiko Alonso. Before the trade, McCoy had spent his entire six-year NFL career with the Eagles, and had just finished third in the NFL in rushing with 1,319 yards to become Philadelphia’s all-time leading rusher.
When the Bills and Eagles played in December, McCoy vowed not to shake his former coach’s hand or talk to him. He said he has still not spoken to Kelly since the trade.
