Id take Parker.
Its sorta of a gamble, but not that much risk.
Parker fits our team, our city, everything better.
Parker costs less
Parker is bigger. He gives us a better chance at winning championships if he pans out. Harden isnt ever taking down Lebron or KD types. Parker at least has a chance. Also, Harden has to battle KD and Lebron right now. Parker will be in his prime when Lebron and KD start going downhill. Parker will probably be one of the best in the NBA at that point.
We know Harden doesn't play D. I think Parker still has a chance at being a better defender. I dont buy that he cant play D yet? Ive seen some flashes of excellent defense.
Lets also not forget that Parker is still a freshman in college and looks like he could be an allstar in the NBA right now. Parkers ceiling is higher.
Again, it would be a gamble, but its a gamble Im taking. I believe Parker is the real deal. I believe he will surpass Harden at some point before Harden is out of his prime, and just his overall career effectiveness as well.
