Harden may carry the Rockets to one win but I agree it's most likely to be a Warriors sweep. Houston and Chicago were the big under performers this year.
Actually Portland finished all the way up at the 5th seed! Incredible performance in a rebuilding year. They are matched up with the Clippers, the worst of the top 4 seeds. If they can push them to 6 games that will be a huge success.
But yes, it should be Warriors vs Spurs in the WCF. And I think whoever wins that will take the title barring injuries to their top players. Cleveland just don't look like a championship team to me.
