I think it's plausible Wlad chokes and gets stopped, but their records and styles indicate what's likely is Wlad wins a wide, boring decision.
People don't talk about this, but Lewis tamed Tua by coming out aggressively and immediately putting hurt on Tua, and instilling fear in Tua. Pussy Wlas would never take that approach.
A prime inshape Tua needed to cheat shot Hasim Rahman to beat him. He ain't be Wlad unless Wlad choked.
Plus, prime Tua got soundly outboxed for ten rounds by inexperienced Oleg Maskaev who had nothing over Wlad, not even chin. I get it that if Brewster did it, Tua has a chance too but there are a lot more examples of Tua struggling or losing. The guy just wasn't the same as his highlight reel, which admittedly is remarkable
Yeah I've got to go with Wlad here, there's always a punchers chance with Tua but I can never trust a guy who throws as many rounds away as him. Wlad UD, too big and too good.
