What meaning? The club never won a premiership as The Lions and had 10-20 odd years of absolute s**t to go through before they were finally put out of their misery with the merger. The ONLY positive connotation that the Lion logo holds is the threepeat of Brisbane.
By that logic I should have had no attachment to the Swans' red & white colours or name until 2005 seeing as the club hadn't won a premiership in them during my lifetime, and had been through all manner of misery.
Meaning isn't bestowed upon colours, a name or a logo by success. If I was a Fitzroy supporter my pride in that logo would be derived from its survival against all the odds, I suspect.
