Breh Brown didn't trip. Sherman pushed him down. It was very blatantly illegal contact and it led directly to a pick which led directly to a TD. But they let Sherman do whatever he wanted out there. Was grabbing and pushing and shoving all game long.
Ben should have tried to make a proper play instead of trying to influence the refs into calling pass interfernce.
It was obvious what he was trying to do. Too bad the refs let the players play in Seattle.
