Makes no difference what you call it. Gary Hart should be on it.
I suspect there are countless players over the last 113 years that warrant being on a banner ahead of Gary Hart and that is not to diminish the service he gave the club. Charlie Webb isn't there (although I believe he is remembered somewhere in Dick's Bar) and neither is John Jackson, our first ever manager. There are also many iconic moments, what about Teddy Maybank, scored our first ever goal in the top flite.
As dislikeable as Leon Knight is, I would agree that his goal in 2004 is more iconic than scoring the first goal at Withdean and the Amex. Others may disagree but at the end of the day there can't be a banner for everyone!
