Vikings wide receiver Bernard Berrian has seen his time on the field reduce as the season has advanced. Now, he may be angling for a trade after Minnesota added Randy Moss via trade. "Anytime a player's reps get cut or anything of that nature happens, a player's never going to be happy. But it's just the way ... my attitude has to change," he said. Berrian's decreasing role appears likely to reduce even further with Moss is town. "You guys are talking about roles," said Berrian. "It's hard to figure out your role when stuff starts getting chopped."
