Andre Ward analyzes Jake Paul vs. Nate Diaz - "A tougher fight than people realize"

Boxing great Andre Ward, who has worked extensively with Nate and Nick Diaz, recently broke down the matchup between the Stockton native and 'The Problem Child'.

Ward believes that Jake Paul vs. Nate Diaz will be far closer than people expect. The stark contrast between the athleticism of the two fighters has led many to believe that 'The Problem Child' will defeat Diaz without issue.

However, Andre Ward knows that the bout will be a competitive affair.

The former boxing champion recently appeared on The MMA Hour with Ariel Helwani and broke down Jake Paul vs. Nate Diaz. He said:

"[Nate] has got some miles on him. He's been around a long time so he's got to show that he can take a shot from Jake Paul. Jake has a natural right hand, it's got power on it. If he can take that right hand from Jake Paul, it's gonna be a tougher fight than people realize."

Andre Ward feels people "misread" Nate Diaz's boxing 🥊

"If he can take that right hand from Jake Paul, it’s going to be a tougher fight than people realize, because Nate’s going to keep coming.”
