Which player proved the most in the Summer Leagues so far?

Some candidates: Von Wafer (24 ppg, 42 points in 27 minutes of the final game), Nate Robinson (MVP of the Vegas Summer League, just under 19 ppg), Kevin Durant (scored a lot although not very efficiently), Al Thornton (17 ppg), JJ Re (played well in the Orlando Summer League, first team All-Star there), Tyrus Thomas (over 20 ppg in his appearances in the Orlando Summer League). Out of these guys and everyone else, who was the most impressive?
