Fans get mad when players sign with rival teams. It will happen until the end of time.
But former players should know better. Tiki Barber doesn't.
Barber, a former New York Giants running back, took the time on Monday to criticize Saquon Barkley for agreeing to a new deal with the Philadelphia Eagles, who are the Giants' NFC East rival.
Barkley wanted a long-term deal for a while. He was vocal about it last year when he got the franchise tag. The Giants didn't give it to him but he got a good deal from the Eagles, agreeing to a three-year deal worth $37.
