Plenty of players test positive for performance enhancing drugs. But the Seahawks definitely are in the midst of a troubling trend.

As pointed out by Eric D. Williams of the Tacoma News Tribune, defensive end Bruce Irvin has become the sixth Seahawks player to test positive for performance enhancing drugs since 2011.

The others are cornerback Brandon Browner, safety Winston Guy, offensive lineman John Moffitt, offensive lineman Allen Barbre, and cornerback Richard Sherman.
