According to the ESPN play-by-play of the second quarter of the Lakers' 102-89 Game 1 2010 NBA Finals victory, Derek Fisher took the last shot from the field, but Pau Gasol took the Lakers' last shot of the half (from the free throw line). Yes, there was some ambiguity here, but luckily I'm saved because no one picked Fisher anyway (whew!).
I've got to think of more clear rules for this next round, which will take place during Game 2 on June 6 (I hope that's 2010). Any ideas, o brilliant SOSG readers?
