Paul is good PG, if we will compare him to westbook, we must need to focus on their rule and thought westbrook has some good stats but you can see how Paul will impact in the floor especially in though times. The previous playoffs when they face the Warriors in the WCF, the rockets had a better chance of winning if Paul was available in game 7, and prior to that, he help his team a lot as he is very consistent than Harden.
I'm sorry but I'm not buying that argument. Him and Harden are healthy this season but still GSW beat the without Durant on the floor. And CP3 and Westbrook are not comparable, of course both of them can bring impact to the team they play, but that's about it as far as comparison it.
If you wanted to compare Westbrook, it will be on Harden, two good ball players so chooses to seek more statistics under their belt but totally choke on playoffs.
I don't think either one of them will or can adjust. They both play similar so I don't know how it will impact Houston now.
