It's all about health..... the question is, how much do you want to bank on his continued good health?
Jose has the offensive skills to be one of the top offensive facilitators (not top pg's, big difference) and it's shown with his absence at times. For all the Kyrie hopefuls that think he'll just come in and save us, look at Washington. This team just needs to stockpile best available for a while and wait for a point in time to make a major move to acquire bigtime talent, if it doesn't eventually emerge from within.
In the meantime, let's hope Jose stays healthy while this team continues to grow and develop. He's done wonders for Amir's game already.
