A lot of Gatti's entry is based on sentimentality really, what with his passing being not too long ago and many of the BWAA people having followed his career pretty closely. In an ideal world, a place in any sports-related hall of fame would be reserved for true, elite "greats". Well, at least I'm guessing that would be most people's view, but I suppose at some point you're going to have a shortage of those and it then becomes a bit of a popularity contest.
