Couldn't see all of it, just the final minutes, but i've seen Garbajosa a lot of times playing for Spain.
He's a great shooter with 3pt range, and barely misses his freethrows. I remember one game with spain in the last european championships where he scored like 18 FTs without a miss. He's not afraid to take the bigs shots. In fact, he's used to taking them.
I think he can do well in the NBA, but i'm not so sure about how he would do in defense. He's got a lot of experience in important games and he'll be a good backup PF/C for Toronto.
