Seems pretty obvious to me; Battle Of The Babies. Winner gets to keep the name and call himself the OG.
The guy he lost to could be the best HW. Hes in the same boat as Frank Sanchez where we really aren't sure how much to hold the Bakole/Kabayel losses against them. One thing about Anderson is hes the best prospect whose actually a prospect. Most of these other "prospects" are really just 30 year olds who haven't fought for anything. Anderson really is a prospect and hes really got criticized too much for not caring.
He's not really in the same boat as Sanchez given that he's a lot younger and lost to a better boxer. Anderson was overrated, but he's still a decent heavyweight. Sanchez, with his gynecomastia, was injured (knee, I think) in his loss but the clock is ticking for him and he's an extremely boring boxer regardless, so I'm not arsed about seeing him again.
Anderson talked up retiring at a young age in boxing so I am not convinced his head is in the game. He'll have some come back fight for sure against some journeyman like Christian Hammer he'll need the money.
Most time younger fighters say something like that they are lying and don't follow through. Younger people do not understand time as well from a perception standpoint as a year is more time to them. Later on when the years start racing by they change their tune.
