As had been said, they had a helluva first appearance but after Medusa left they dropped off considerably. Multiple attempts have been made to toughen them up, but nothing stuck. Even in Dan Slott's last Wizard story in FF, the Wizard was out thought by his Bentley clone. The Wizard himself is a college QB trying to beat Tom Brady. The Trapster could be gimmicked up to be a reasonable henchman, but really is just a henchman. Sandman is far more interesting as someone who is playing around the hero/villain boundaries. As far as story potential goes, you might have three guys who have some sort of friendship, and may back each other up, but the team as is really isn't a threat. The rotating slot for a fourth member didn't help matters much.
