Eagles defensive end Brandon Graham couldn't help but take a shot at the Cowboys when he was brought onstage to announce an NFL Draft pick on Friday night.
Early in the second round, before Philly selected Cooper DeJean at No. 40, Graham made his allegiances clear in Detroit.
He started off by saying 'Go Blue,' an homage to his alma mater Michigan, whose national championship-winning team was recognized before the second round began.
Graham then started an 'E-A-G-L-E-S' chant before taking aim at their hated NFC East rivals.
'Dallas sucks!,' he said. 'All day.'

The Eagles selected Iowa cornerback Cooper DeJean with the 40th overall pick on Friday
The remark elicited a surprised 'woah' from NFL Network host Rich Eisen on air.
Graham then laughed as the crowd cheered on his fighting words.
The 36-year-old has spent his entire career with Philadelphia since they drafted him in 2010.
The Eagles made Toledo´s Quinyon Mitchell the first cornerback taken at No. 22.
The addition of DeJean fortifies a now-crowded secondary that includes Darius Slay and James Bradberry.
DeJean, who raised eyebrows when he said he could beat fellow Iowa product Caitlin Clark in basketball, was projected by many to be a first-round pick.
