From talking to guys at his gym, Petz seems to be a pretty safe bet against Morgan. I'd say the big money maker in this fight has to be Von Flue over Riggs, because its the risk:gain ratio. He has a decent chance of beating him, and the payout is huge. All depends on if your going to safe bets or huge winners.

Also, be aware that Karo isn't at 100% due to a leg injury. Still no reason he can't beat Diego, but you should be aware of it, as its a possibility Diego could pull the upset.
