The thing with defense is that playing defense requires both trust and sacrifice (stats) and it is not only hard work, but a pace killer as well. So while we fans sit back eating nachos flummoxed that overpaid men are not hustling on defense and that is the obvious reason we are loosing, the truth is there is no point in working hard on defense if you cant trust the other guys to hold up their end. While one superstar can come out and wreck the other team all by himself, no one defender can stop pretty much anyone, the best they can do is force a pass. If the other guys are not working you get worked and tired for nothing. Every player on the team has to solidly agree to work together KNOWING that individually their stats will suffer but as a team they will have a much better chance of wining. So If my coach is pushing pace, and the team is not stressing defense why should I give up my scoring, or assist numbers by working an opponent? This is especially true if I can't trust my teammates to defend once the pass is made. I might as well just look for shots and open guys and try to outscore the other team. This is exactly why we call uber-high scoring games junk basketball, not because of all of the dunks and made 3 point shots, by INDIVIDUAL players but because of selfish nature of a bunch of guys who playing for their numbers on the offensive end and unwilling to work the other end for the TEAM.
Sadly few guys take anywhere as much personal pride in shutting guys down than they do in lighting them up, I wish more players had Bobby J's mature perspective but young players do not, they have to be taught it, and that job falls upon the coach their staff and veteran players. If it was just a matter of using the defensive skills these guys have developed over the years despite coaching, trust and practice and just playing with a sense of pride, the All-Star game would be a meat grinder as personal pride and a deep bench meant the biggest egos in the league would be competing to shut each other down.
