I don't profess to be an expert but Wolf has always wanted it but Ali has been able to stay famous and earn well fighting the Valerie Mahfood's (sp) of this world.
I believe Laila has retired to make babies now.
she is still listed as active in the boxrec rankings, I guess wolfe has a reputation for hurting people and can understand not wanting to be hurt if you don't have to... its a shame because there is not much in womens bocing which could spark interest of the wider public.
