Any true Russian hockey fan yearns for the return of the Soviet school of beautiful and dominant hockey. It was almost like an art form, like the Bolshoi Ballet on ice, so beautiful to watch. But, as Larionov personally attested, being the loudest and most vocal critic of the Soviet hockey school back in the late 80's, it is an absolute bitch to train for. Soviet teams logged practice times, consistently, of 13-1400 hours of practice each year. The training was so grueling that Tretiak noted that "we pissed blood!" So you can't just throw 20 guys together who barely know each other and install that kind of intricate system for a 10-day youth tournament.
One of the hallmarks of the Soviet school was its focus on "muscle memory." In practice, everything was done at the fastest possible speed, even if passing was off the mark. In games, Soviet teams played at such a speed that it looked like opposing teams were standing still. In contrast, the Nutty Professor's system focuses everything on a slow build, constantly dropping backward passes to regroup. That made the Czechs job incredibly easy by allowing them to leisurely line up 5 defenders in the neutral zone, let the Russians play with the puck in their defensive zone as long as they wanted, but when they finally decided to come out, it took away any passing options and forced them to stickhandle through 5 defenders to get to the blueline. Now that the Nutty Professor's system is exposed, he faces the daunting task of trying to install changes with only two games left until the medal round.
So, is the attempt to revive the elements of the Soviet hockey school a lost cause? Not necessarily. They could do what Herb Brooks, USA coach of the Miracle on Ice did in advance of the 1980 Olympics. They could enter a Russian U20 National Team in the KHL or VHL for the full season, with the games counting in the standings, to avoid any "exhibition game" mentality. The boys would become men, and they would be tough to contend with in future WJC's.
