Why I will not bet on Josh Barnett:

He is old and looks like he has aged a lot.

He has not fought since UFC 168. Anderson Silva's leg fell off that night and he has already had a fight since then.

Drug testing. Have you guys seen recent pic of Barnett? He looks like he lost a lot of size.

He is also going to retire soon IMO. He seems preoccupied with pro wrestling and coaching.

I am going to bet Nelson as a fade to Barnett.

However, this worries me:

Mir was able to out wrestle and out cardio Roy Nelson. LOL
