If you're going from January 1 to today, it is really tempting
to go with Aizpitarte. He went from a shaky kid to potential late
gamer in a year. I agree with PP's assertion below. I think he
could be in late games before the end of '10.
That said, I'm giving the award to Aritz. He was playing a lot
of earlies just last year and now look at him. He will be their
#2 frontcourt guy by 2012 and that is saying something.
