Teams without good jump-shooters, with range on their shot, end up taking more jump-shots. And then you have bad jump-shooters taking them.
That's why a team like Roy Hobb's Blazers wouldn't win more than 15 games in a NBA season.
Generally, fans have an unreasonable preference towards "attacking the rim", "dunks", "low post", etc. Aesthetically, they may have a point.
But Coaches have to win games...
I think you need to have a balance to be successful, but in general, I agree.
Many people seem to think that the only high percentage shot is a layup. However, when you look at the best teams in the league, they are filled with good shooters. This is because an open jumpshot for many players in the league is nearly as high percentage a shot as an open shot in the post. And the real key is that an open jumpshot is a higher percentage shot than a challenged layup, and it is MUCH easier to get an open jumpshot in the NBA, than an unchallenged layup. Therefore the teams with good jumpshooters (Celtics, Spurs, Pistons, Hornets to name a few) succeed because they know they can get a higher number of high percentage shots than those team who rely much more on layups for "high percentage shots" (the teams that come immediately to mind here are charlotte and Philly).
Yeps. More than that: teams who rely heavily on "high-percentage shots" are too easy to defend.
You can have a team filled with the best slashers and the best low-post players in the game. The Greatest of All Times if you will. You still won't win.
The opponent will simply use a 2-3 zone defence. There's only ONE WAY of beating a 2-3: good outside shooting. Doesn't matter how good are your players doing other things. Even the team with the worse defence on the league will get stop after stop after stop.
Highly-percentage shots are fool's gold many times because they cause turnovers.
And turnovers are the most underrated stat in basketball, from the fans point of view. In a game with 2 teams with a 50%TS, each turnover costs you 2 points. And generally teams have a better shooting % after turnovers from the other team. Turning over the ball is basically giving the other team a free basket.
That's why limiting turnovers, taking good care of the ball and
having creating proper space is so important. Winning teams generally do this.
ps - case in point: you hear a lot things like "Bowen was so lucky to play with Duncan and having all those open shots from the corner" or "Jordan made Kerr look so good, all he had to do was taking wide open shots". But it works both ways: without Kerr and Bowen being threats from the outside, Duncan and Jordan wouldn't be so effective. And you rarely, if ever, hear that. Of course Jordan helped Kerr more than the opposite and it's not even close, but there's always a trade-off.
