Well, for this year's "Biggest Party of the Summer", it's the focus of the main event because.......
WWE Universal Championship and Tribal Chief position in the Anoa'i/Fatu family (Tribal Combat Rules) - Roman Reigns (c) vs. "Main Event" Jey Uso: Basically, it's a glorified No-DQ match, perhaps with the participants wearing Samoan garb. It's Reigns' first televised title defense since WM39....OVER FOUR MONTHS AGO. That's ridiculous. More to the point, Reigns hasn't won on PPV (or PLE) since then. Jey pinned him in that tag match at Money In The Bank. Now, because Reigns and Sikoa put Jimmy Uso on the shelf, the elders have declared some sort of crisis. Thus, it must be settled in "Tribal Combat", with Reigns' role as head of the family on the line along with his belt(s).
I smell a heel turn for Jimmy Uso. Reigns is a few weeks short of a full three years as Universal Champion. Jey will put on a show; but Jimmy will swerve him and Reigns retains.
WWE World Heavyweight Championship - Seth "Freakin' " Rollins (c) vs. Finn Balor - The seven-year anniversary of the finals for the inaugural Universal Championship, only it's just bitter Balor with no Demon.....yet. Add the specter that Balor's Judgment Day buddy, Damian Priest, has been teasing a MITB cash-in, and it makes for interesting fodder. For some reason, I don't see a title change. Rollins is still too over. Maybe before 2023 ends, we'll have Priest pull the trigger....BUT PLEASE DON'T LET HIM DO THAT FOR THE IC BELT!!!
WWE Women's Championship (Triple Threat): Asuka (c) vs. Charlotte Flair vs. Bianca Belair - What the heck! UPSET SPECIAL (of sorts): A heel turn for the sweetheart of WWE, Bianca Belair. And the perfect way to introduce that would be having Asuka retain after Flair stops Belair from getting the pin. Then, let Belair get medieval on Flair and leave her laying.
WWE Intercontinental Championship: Gunther (c) vs. Drew McIntyre - Totally bias here: I'm rooting for McIntyre, because if Gunther retains, they'll let him keep the title and he'll pass Honky Tonk Man. I'm sorry! The Honky Tonk Man is the greatest Intercontinental Champion of all time. Or as Solomonster put it, what is Honky going to do without that record-long IC reign as his claim to fame? Their match at 'Mania (along with Sheamus) was absolutely smash-mouthedly delicious. Hopefully, McIntyre won't have all those welts on his chests as Sheamus did last year. Maybe they'll give McIntyre his consolatory WrestleMania moment, where he wins a title in front of a stadium of fans (to make up for his empty-arena WWE world title win at WM36). Then, he won't be the Thunderdome champion, anymore.
Brock Lesnar vs. "The American Nightmare" Cody Rhodes - Lesnar apparently is booked in another match that's the "final chapter". Just as last year was his "last time" facing Roman Reigns, this is supposedly the final time (the rubber match) between the three. But, there are no special stipulations. If Rhodes is still going to try and "finish the story", he has to beat the Beast. I'm sure Lesnar is tired of jobbing at SummerSlam. I'd give Rhodes the nod, if there were only one world title. But, now he can still "finish the story" even with a loss. I don't know if it was officially announced, but it was implied that the winner get Rollins for the world title (assuming Rolling retains). I'll reluctantly go with Rhodes.
SummerSlam 25-Man Battle Royal - At least this in on a PPV, as the ATG Battle Royal is scrapped from WrestleMania show altogether. Well, since he surprisingly didn't win the US Title Invitational to get a shot at Austin Theory (who ain't defending his belt at all ), it appears this has been all but gift-wrapped for Shaun Ricker/Max Dupri/LA Knight.
MMA RULES: Shayna Bayzler vs. "Rowdy" Ronda Rousey - This appears to be a train wreck in the making. Rousey lost to Liv Morgan last year. I don't see her jobbing again, or her stock plunges further. Rousey gets the win.
Logan Paul vs. Ricochet - This beef started with their confrontation and mid-air crash at the Rumble. It escalated because Logan Paul didn't have to qualify to be in the MITB match. Now, to add to it, Paul is making is personal by dragging the ring announcer, (Samantha Irvin, Ricochet's fiancee) into the fray. Get ready for lots of moonsaults, high spots, and perhaps a slap across the kisser from Irvin to Paul. I think Paul gets the win, as I only remember his winning at SummerSlam two years back against the Miz. Logan Paul's status isn't worth all that much, if he keeps losing. Plus, he wants to get in and out, so he can fly to see his brother fight in Dallas.
