How about Lars? Remember how bad Strow Man was when he first joined the main roster? Lars goes and has a 4* match (albeit with one badly botched spot). Lars needs to be Smackdown's Strowman or something.
And god it must suck to be Aleister Black's opponent, dude does not care one bit about kicking you right in the FACE

Lars looks like he was in a real kickboxing match
