Sweden had Vikings but no, he’s not Swedish, he might been born there but from Finish parents, he claim to be Finish and fought amateurs based out of Finland. I know because I’m a Swedish Viking and I was supposed to fight him in Finland in an amateur fight. He’s Finish and Finland did not have Vikings.
Working on fundamentals (that takes years to perfect) after his prime won't help LOL Happens way too often in declining fighters.
You right. I used a hyperbole in the post. Its almost impossible for Wilder improve his fundamentals above all if he lacks them.
