I would like that to happen but there's not going to be any real money in that fight (not even a fraction of the half mil. like last time), so I'll be amazed if it happens.
Also, is he going to train at Duke's again? They would expect the same money as last time (and that would eat up any profit from the fight).
Is he going to train somewhere else? He didn't even hardly train last time (you could tell he didn't put in the work, I've never seen someone do so badly after 6 months at a gym, let alone 2 years). Is he going to actually train this time?
There's just too much awkwardness in the logistics and not enough payout (plus only further embarrassment to a childhood icon), although I would really like for this fight to happen. My guess is he has to pretend to entertain the idea so he doesn't look like a chump who got beat once and ran, that would be really bad for his brand especially while he's doing reality TV and things like that.
