IRVING -- A disgruntled Dallas Cowboys fan who decided to show his displeasure over the team's dismal season and embarrassing performance in the 44-6 season finale loss against the Philadelphia Eagles got more than he bargained for on Monday outside the team's Valley Ranch training complex.Alan Lowe of Richland Hills marched up and down Cowboys Parkway wearing a sign that read "The Cowboys have no heart" on the front and "Wade Phillips is a embarrassment to the Star on the back."Lowe said he was attacked by linebacker Bradie James, who allegedly threatened to beat him up because he didn't take the sign off. According to Lowe, James tore the sign off his back and broke his golf glasses in the process. Lowe called the Irving police and intitially attempted to file a report."I wanted the players to see what the fans think," Lowe said.James said the guy was in the street and almost hit him with his car.But he did acknowledge threatening Lowe and taking the sign, especially after he said James showed more emotion on Monday than he did Sunday.James returned to the Cowboys complex and re-gifted a pair of Oakley sunglasses to Lowe."He said, ʽWhy you guys didnʼt show that fire last night? You should have showed that heart last night,'" James recalled."So next thing you know, Iʼm just ripping his sign off him. So I ripped the sign off him. He said I broke his glasses, so I went and gift-wrapped some Oakleys. He got something out the deal.""I wanted them to feel what I felt last night," Lowe said. "Bradie is actually one of the guys that plays with heart."James said he apologized and gave him a handshake but said Lowe was still out of line."I told him, 'I share your frustrations. But where we differ is I wouldn't go to anybody's job, especially not with 300-pound guys, trying to tell them what they didn't do right,'" James said. "But that's it. It's over."Lowe did not file a police report.
