Newcomer Fan

I'm relatively new to boxing. I've grown up around boxing. My mother's a huge Ali fan, my dad loves boxing, etc. But I never really got into the sport until about August. So now I feel like I'm playing catch-up with all the aficionados here. I have a good collection of fights, but are there any fights out there that I really need to see to understand boxing as a sport? Or any fighters who may have slipped through my fingers? I'm a huge Marquez fan and I'm doing everything I can to watch all his fights, but there are still names that get bandied about here that I have never seen. I know you guys hate on people who don't eat, sleep and breathe boxing, but any suggestions you have would be great.
