not even a little bit. when they say 76 percent of the teams who've gone up 2-0 end up winning the series, it does not mean that the team up 2-0 has a 76 percent chance of winning the next game, it means that if there had been 100 teams in similar situations, 76 of them had gone on to win that series: historical pattern. this is a historical pattern: three teams have swept the first two rounds, three have gone on to lose the next round. the pattern has fewer numbers so there's that, but no less the same kind of thing as the 2-0 thing. it would be insane to think that two teams facing each other suddenly increase their chances of winning a game solely by virtue of having won a previous one. all the components remain the same, so all the probabilities remain the same, too.
