The Cowboys are scrimmaging the Raiders. Guess what! There was fan "interaction" with the Cowboys.
Here's a close up. From Yahoo!:
But it happened right next to a section that contained mostly Raiders fans, and one took a full-sized replica helmet and swung it at Cowboys cornerback B.W. Webb. Webb responded by giving a hard shove to the fan. Luckily the situation didn't escalate. Here's a Vine video from Channel 5 in Dallas' coverage (Webb is wearing No. 20):
Very easy to make this into a "Raiders fans be all like Raiders fans," but there's something important about this melee. The gang problem in LA is significant. And at the end of their tenure in LA, the Raiders were drawing a criminal element to their games.
Does the NFL want a team in LA? Probably. Do they want THIS PARTICULAR TEAM in LA? If the Rams, Chargers and Bills are also free agents?
