What's wrong with trading for Harden and giving him that contract if Harden is only good enough to be the #2 guy on a title team?
Harden doesn't need to be a #1 option on a title team for this to be a successful trade / signing for Houston.
Pippen would be the poster boy for this, considering his lack of success without Jordan despite being such a vital part of the Bulls' championship teams.
The whole #1 option idea is probably irrelevant since winning isn't just about scorers. KG hasn't led us in scoring, but his impact has been the greatest due to our reliance on defense. Someone like Stockton was clearly worthy of a max deal, but would never be a team's leading scorer because his contributions were more pronounced through running the offense and defending.
Still, if Harden is going to average high 20s in PPG, he will probably be the #1 offensive option, even if paired with another top player unless it is Lebron, Durant, or CP3 (though Lebron or CP3 would probably get him an open shot at the buzzer if that was the best play). Actually, my comment is premature. Harden still has to prove himself as the guy in Houston. But is it absurd for people to close the book on him already.
