Tbh, I hope the media doesn't build this up as some huge emotional event for Walt. It won't do him any favors, and will only put unnecessary pressure on the guy. I'll lose my fucking mind if Ariel tries to turn the story into one of his bullshit spins.
Otherwise, I genuinely have no idea who's going to win. My guess is that Overeem may be inclined to clinch and grapple. Tbh though, five rounds is a long time to be in there with Walt, who I believe possess the greater ability to end the fight quick. Regardless, I want to see the winner fight Lewis. If Overeem does end up getting slept, he seriously needs to retire this time. Someone needs to save the man from himself.
