I'm thinking it's between Kawhi and Boris. Kawhi has triggered a lot of Spurs rallies during these playoffs with his timely steals and rebounds while Boris' tenacious defense on the bigs stands out. If he can neutralize Andersen and maybe Bosh and Kawhi can slow down James and the rest of the team stay in front of their opponents, we might just come out of this with #5.
I'm great at multi-tasking -- I can waste time, be unproductive, and procrastinate all at once. Ain't life grand!!
