Even if Orton doesn’t viciously pulverize folks in the ring, he’s still 6’5 and jacked to the point where can wrestle on national television wearing just a pair of wrestling trunks, and the look works.
In comparison, Soulja Boy is quite a bit shorter at 5’8, so if there is a fight between the two, the rapper would likely be hoping it would be of a fictional nature.
What Randy Orton does in the WWE may have a pre-determined outcome a lot of the time, but the physical toll the sport takes on its wrestlers is very real, from backyard brawls to the most professional PPV events.
