That is interesting 2016, but I question that to some degree.
In basketball the offense has the advantage as they can almost always get a shot off that has a chance of going in (Monta Ellis). Add to that the rules on fouling and defensive spacing (3 second rule) and it becomes a difficult task.
Presuming we have all watched college basketball--where the athletic disparity is more pronounced from say, Kansas, versus a smaller school. Yes, offense is easier, but they simply destroy on the defensive end getting steals, rebounds, blocking shots, and forcing difficult shots from the perimeter resulting in tons of fast-break points. Even if Kansas were to suffer their worst shooting performance of the year they would still win.
Offense, in the NBA, is valued so highly because there is not enough of an athletic disparity (for most players) to overcome the handicap put in place by the rules and the inherent offensive advantage. If a team can acquire a player like Dwight, Ben Wallace, Larry Sanders, KG, Lebron, Scottie Pippen, etc. then the defense becomes important again.
Shots are still going to fall, but that must be handled on the other end where, ideally, you also have good offensive players that can then outscore the opponent with greater ease.
This is why no team built entirely around offense has ever succeeded. Offense is generally streaky while defense is relatively consistent.
Every single NBA roster has guys that can "fill it up"...it's the ones that can also lock it down that rise to the top.
