I'm all in favor of this and it was about time. Wrestling has become table tennis 2.0 and in some cases even worse. In European Championships from 20 wrestlers in a weight you were seeing 7-8 foreigners. Yes, it's mostly Russians, but there are also Ukrainians, Georgians, Cubans being naturalized.
I've said it numerous times, that i don't approve the tactic our federation started of naturalizing people left and right. Which actually wasn't paying off that much, until the Olympics. If it leads to worse results, than it's just a wakeup call for the destruction of our wrestling system (which has been evident for 15 years).
