Of course it's fair. Portland didn't somehow rig the system to make their division less competitive this year. That's just how it played out. But Portland still did the work and won their division. San Antonio and L.A. played well, but they did not win their divisions. That is not Portland's fault. Nothing unfair about it. If playoff seeding was done by raw win/loss record, what if Portland got edged out by both teams, but it was clear that both teams got a lot of wins they "did not deserve" because, as luck would have it, they beat good teams during times when those teams had a lot of guys out for injuries? Would that be unfair? No. There is no perfect system either way because there will always be circumstances you cannot anticipate. But again, division leaders are given the advantage in playoff seeding in a LOT of sports, not just the NBA, and there is nothing "unfair" about it.
