Well, since this seems to be a who's who list of former Celtic scrubs, let me add Ed Pinckney, Brad Lohaus, and Kevin Gamble. Actually, Gamble wasn't all that bad.
But I doubt that some scrub from 20 years ago is the "password." It's got to be a decent player that newer fans wouldn't remember - somebody like Wedman, Sichting, etc. Did someone mention Sherman Douglas already?
