I've been thinking about this defense, not offense quote. Actually, JL has consistantly said all of his players should work hard on defense, then good things happen on O.
When POB was a frosh, he had a real, real, real strong first 5 games (He was top 10 nationally in blocked shots/game, shooting % and top 10 FT% for centers) JL then started saying, "We need to get POB more touches", "We need to get Cellus and POB more touches" "They need to touch the ball more", and that big man, offensively minded approach got us about a year and a half of nothing. POB's production dropped the more we tried to get him "touches" and Cellus started to get a reputation of a selfish player, to his team's detriment. POB's probably been battling against that "O only" mindset in the NBA, and JL does no want to repeat that mistake. Once guys like JJ started to give up defining themselves by offense, the team started playing really, really well and we got our S16 run.
Really, if our centers "only" play strong D and rebound well, they will get more than enough "garbage" (Other than AW, our guards are too good at creating garbage) to cleanup on O. More O then they would otherwise get as a focal point and we will be a better team...
