Same: The defense will be solid -- Defense has been a trademark of Doc Rivers's teams since Garnett arrived in Boston in 2007. Garnett has had a lot to do with that, but it's also a team concept that makes it happen.The Celtics finished second in the league last season in opponent points per game at 89.3 They could be even better defensively this season with more playing time for Avery Bradley and with the additions of Courtney Lee and Jeff Green.
