Say what? So a team that wins a closely contested 7 games series is "clearly" the best team? Don't think so.
Well it's the best way anybody could think of realistically. I'm an avid NBA fan and a casual NCAA fan outside of ISU. Of course it's possible to have years where the best teams are an eyelash apart.
There were only three times in the past 35 years where I thought the best team wasn't crowned NBA Finals champion. It was officiating/scandal related and not performance related. (Kings, Suns, Mavs were the three that were at least somewhat robbed by scandal imho)
You could argue for something like the EPL soccer title where if we applied it to NCAA basketball we'd care even more about the Big 12 regular season championship and we all ignore the NCAA tourney and Big 12 tourney...but I actually think that isn't any better in some ways.
For example the '95 Rockets were only a 6 seed but I consider them one of the better teams of the past 35 years. They had the best player in the league that year at his peak, they defeated the top 3 seeds in the West on their way to the finals and then embarassed the East champ. An EPL style champinship says they were about 9th in the NBA. Long playoff series are simply the best way to determine the truly best team. Doesn't work for college basketball and the current college format is crazy fun, but we all know the best team doesn't get crowned in the NCAA tourney every year or even most years. If Gonzaga wins it this year it will be one of those years where the team everyone thinks is probably the best is the champ.
(nothing special about 35 years other than that's how many Finals I have watched)
