Rio just never had it going in CS:S. I don't know if their teamwork was hurting because "bit", a longtime member of Made in Brazil, couldn't compete in the CGS, but they looked overmatched from the start.
As for the individual players, Harriman played incredibly well for Birmingham, but RattlesnK was just even more impressive. His AWP was crucial on the Salvo's T side attack, and he picked up kills in bunches.
For Rio, cogu, bruno, nak, and Jorinho all played well at times, but never together. Cogu would get 2-3 kills in a round, but nobody else did much. Then nak would have a good round, and bruno would get three kills the next round. They just couldn't put it all together.
