If that is what he meant then he is right. The playoffs are anti climactic and pointless.
The finals on the other hand might be great. Or suck. We don't know yet
Are the Finals not part of the playoffs? If the NBA season was a storyline the regular season is the origin story, the initial rounds of the playoffs are the part where you meet the bad guy and find out his evil plan, and then the Finals are the final battle. Anti-climatic means the ending was not what it was built up to be, a let down at the end. If the Cavs/Warriors series sucks, then it would be anti-climatic. If it's amazing then the playoffs would be extremely climatic.
The problem is the part that is building up to the climax. That doesnt mean it's anti-climatic.
