Those Russian OHs you mentioned are not exceptional players, but if they could be exported, I'm sure many NTs would welcome them and they could even be starters. There're not many OHs who can spike and receive well nowadays.
Starters sounds yumm :).
Many players will look OK when they have someone like Pavlov playing alongside. In December 2010, Loko Nsk with Pavlov and Butko simply destroyed the star-studded (Ball, Tetukhin, Mikhaylov) Zenit Kazan 3-0. The OH of Loko Nsk were a pair of stunts (Anton Dubrovin and Nikolai Leonenko)... I think they ended up somewhere deeply on the bench if not in the 2nd league, with Bratoev G :). The 196 cm tall Kolia Pavlov has been definitely the best opposite in Russian Superleague for several years. He's so good technically and he has a killer instinct.
Brazil was playing a very shaky game yesterday. They actually did so in the first game of the tournament. You may remember that the sets the Brazil won on that day were very tight and the refs helped them a bit, while those won by Russia had like 8-point margin.
