Blazers vs Nuggets is a tight one. This series might go six or seven games.
I think that's the great thing about it - Harden is not tall, not fast, but he made a record of more consecutive 30-points than anyone except since WIlt Chamberlain who was a giant playing among boys.
His stepback move is making the NBA and media revisit the rules as it is nearly unstoppable unless you foul him and not get called (happened a few times in Game1). Much like Kareem Abdul Jabbar's sky hook which was unstoppable during his time.
