I used to feel the way that you do about Tikhonov, and I have never been a fan of Larionov, although his hockey talents and skills were immense, but I have changed my mind a bit. One thing that influenced my thinking was the YouTube video of the ESPN (US Network) documentary "30 on 30; Of Miracles and Men." What struck me was how much players like Tretiak, Petrov, Mikhailov, Yakushev, Fetisov and others absolutely worshipped Tarasov and absolutely hated Tikhonov. Both coaches held training sessions that would literally split your testicles in half, but the reaction from the players to the two was exactly opposite. They universally conveyed their sense that Tarasov loved his players and made their training fun, was like a father to them, while Tikhonov was like a KGB cop who was intent on extracting blood from them!
There is no doubt that Tikhonov contributed some major advancements to the game, particularly in the science of muscle memory, but by the late 1980's, things had changed. The post-war generation in the USSR, the likes of Firsov, Aleksandrov, Mikhailov, and Petrov were phasing out, and the newer generation had experienced less of the hardships of that era. To learn Tikhonov's system and get up to his level, the work effort was herculean but the rewards were almost nonexistent. They earned, in rubles, less than 5,000 in dollars, in comparison to even mediocre NHL players of that era, who earned $400,000. Maybe they had access to a decent apartment, decent food, and a car, which many Soviet citizens did not have, but what little they got was a pittance in comparison to the massive year-long workload they had to endure! In the end, it was simply no longer worth putting up with Tikhonov's crap. They would either go to the NHL, or retire early. They went to the NHL.
It is easy for us fans to expect our players to be great patriots and sacrifice everything with little or nothing in return for their efforts, but in the end, why should they bother? The system simply failed to make it worthwhile to keep on killing themselves.
