Who are the guys (in any sport) that for a period of time were great (and you saw play).... but are now largely forgotten?
Maybe they only flashed, and didn't have HOF careers. Maybe they were just solid players overall...
One name that stands out to me is Juan Gonzalez. I do think of him whenever the '93 Home Run Derby comes up, because his homer to the 3rd deck in LF was just as ridiculous as The Kid hitting the Warehouse.... but this was a guy that was a 2x MVP, 434 career homers... and he generally seems to be forgotten overall.
