The Raptors played Bargnani at the 3 a few times this season. It was Bargnani natural position in Europe, btw. Of course, in Europe teams can play zones the entire game and that allowed Bargnani to play on the perimeter; but in this experiment for the Raptors that 3 big men line-up (O'Neal, Bosh, Bargnani) was a colossal failure. Bargs cannot defend NBA wings, he simply misses the tools to do that.
