For me it's like a couple members mentioned before,
if there's enough time to make a play (say, 5 sec or more) I would pick lebron as he seemed to have gain more confidence after the championship and he is better at creating a shot.
but if it's a catch and shoot situation (less than 2 sec.?) I would pick Durant.
A very, very small collector of Jason Kidd in Canada...
Due to some family matter and personal reasons I'll be selling my collection, please feel free to check out my bucket and put down an offer!
