Obviously BOTH need a lot of work.
Teams with an offensive mentality tend to slack up on defense; don't play as hard on D. Anyway, we don't have the super-star 1-on-1 players to be successful at that.
Personally I'd like to see a team out there with a defensive mentality. Play HARD for 48 minutes; we've got the depth to not have to worry that much about fouls. On offense we need to maintain that same aggressiveness in every aspect; play with focus and SMART, pass the ball with a PURPOSE, not these marshmellow passes I see way too much. And that goes back into the Sloan era too, when DWill and AK were the only decent passers on the court, and sometimes Memo.
