Curious about the spreads in volleyball for the Olympics

[jrmartin.mig]

So for instance, the spread for today's Russia v Bulgaria match is Russia -2 1/2. Does that mean they have to win by 2 1/2 sets? If they are playing first to 3 does that mean that they have to sweep the match to win? I can't imagine that its -2 1/2 total points, but am not sure. Any help would be appriciated.

-2,5 means they have to win all 3 sets for you to win

So they have to sweep the first 3 sets. Interesting
