I don't get why MMA fans are oblivious to the fact that Sweden is arguably the top wrestling powerhouse on the planet.
84 Olympic medals to the US's 125... with like a 30th of the population.
Or look at it this way, Finland and Sweden combined have 167 Olympic medals to the US's 125... with a 20th of the population. Neighbouring countries that have an area smaller than the size of neighbouring states Texas and New Mexico.
Assuming that Gus wanted to brush up on his wrestling to get ready for Jones, he was in the right place to do it.
