I don't really have a huge interest in this fight as their size and age gap is a little too much for my liking.
It sorta feeds the skill vs athleticism questions but I'm not really interested in either of this fighters dropping their first loss (for Silva in the UFC) on a fan fight. It sort of takes away some of their mystic in their own divisions.
Anderson has everything to lose and really not a lot to gain. I believe Jones has more to gain and less to lose but really not worth it IMO.
