Mine was Glenn Robinson. I remember playing NBA Live 2002 when I was real young (born in the mid 90s). I just thought it was really cool how the announcers in the game would refer to him as Big Dog. Also, he was really good at dunks in the game if I recall correctly. I think I even had his jersey in a really small kids size.
Brandon Jennings and Ersan Ilyasova were my go-tos when I really started to follow the bucks as a kid
