The Boston Celtics have seen their offense take the next step this season largely because of their three point shooting. Brad Stevens has always instilled a system that has been dependant on ball movement, and that has done a great job of creating the kind of looks that have allowed players like Avery Bradley and Jae Crowder to grow into deadly shooters, especially from three point range.
When things started out, one of their biggest problems was that Isaiah Thomas was the only player they could trust to generate offense.
