They obviously have their differences but think about it. Both guys were bosses of their division, so much so that they moved up on multiple occasions. Supremely talented, but maybe overly reliant on talent alone (not calling out anderson on anything, but he could certainly throw some strategy into his game). They end up losing to young fighters in thier own weight class , one's with a wrestling base, and get suprising beat in the stand up. Immediate rematches are made; BJ lost the second fight more convincingly than the first and he was never the same fighter. Is that the fate of Anderson as well? There is another aspect of their similarities, one that somewhat contradicts what I just said. Often BJ and Anderson are talked about in terms of talent, but truthfully, they might be some of the most athletically gifted fighters as well. It's interesting that despite their success you can still have people nit picking their game, and questioning their motivation/ work ethic. Maybe it's their attitudes, but its sometimes bizarre how often the mental game of these guys is questioned.
