Pierce vs. Allen in the final round would be sweet (except that last year didn't they have 3 players in the final round, not quite as cool if it's Pierce vs Ray vs somebody else).
Also both Pierce and Ray have won the 3-point contest once already, so who takes the overall lead between the two could add to the excitement, just like Kobe one-upping Shaq (so far) in the rings department). It would be so cool if Ray or Pierce won, then the post contest interview went something like this:
Craig Sager: How does it feel to win your 2nd contest?
Pierce: I got one more than Ray. You can take that to the bank.
Not quite Ray's style, but I can definitely see Pierce doing that especially after his "It's been a pleasure to bring my talents to south beach now on to Memphis." tweet.
