No. not on BB.. 2-3 is useless on BB  for some teams.  IN my opinion 2-3 takes luck  tp use.. Its really a wrong scripted made defense.   For starters if it was a zone then where are the steals?  Its seem more like 2-3 man to man than 2-3 zone.
2-3  man to man you'll get eaten alive by pocket mid range shooters in the open ranges all night, on BB that is was happen.. IN 2-3 zone that does not happen , because the defense shifts cover all  spots,HI Od  is working so  is the ID  of the Bigs. On  BB I have never seen  mass steals in 2-3 zone, .  The defense  in 2-3zone on BB to me  is slim to none  or the players are making the best effort of their lives on the court not  to play  defense for some teams.. Maybe with Gdp it  can work.
 
 That  just me, I cant speak for anyone else. That's for them  to come out and say and show. I think is sure a lost defense to play.
