You already said you haven't followed MMA long, why are you trying to tell me about things you don't know about? You can't come up with a decent all time list unless you have watched the sport for a long time and you admitted you have only watched for a few years.
Eddie was the LW champion, saying that's not cutting it in the UFC makes no sense, it makes you sound like you think UFC is MMA rather than just the biggest MMA org.
There have and will always be great fighters that aren't in the UFC, it's been proven time and time again, WEC, Pride, Strikeforce, EliteXC, Bellator have all had fighters come over and either challenge for titles or take them.
