Syb, you are usually right on, but I have to disagree somewhat with the above statement.
If you play great offense and poor defense, you won't win many games because your opposition can game plan against your offense.
If you play great defense you give yourself the opportunity to win every game. Defense includes rebounding, stopping fast breaks, break away steals for uncontested lay-ups, and control of your fouls.
How can you possibly disagree?
First sentence: If your defense is so fantastic that the other team doesn't score, you still haven't won.
Is there any possible disagreement? You have to score at least one point.
Second sentence: Defense keeps you in games. It doesn't win them.
Well, actually, that is two sentences. But, again, you can't possibly disagree. Can you?
Defense keeps the game under some control, but the most definitive correlation, as I have pointed out many times, is field goal percentage. It is very closely related to the best teams in the nation.
When I put forward an analysis of NCAA statistics with respect to ranking, what stood out was that platitudes are exactly that. Defense and turnovers are only somewhat related.
I don't think you can win without a respectable defense. But, I would suggest that once you have a respectable (as opposed to sensational) defense, offense is the key. Teams that don't score don't win. I would rather be in the top twenty percent in defense. But, I would shift the emphasis on the platitudes to offense.
How many players are recruited strictly for defense? We tend to look at scoring averages. You don't see someone recruited who scores six points a game, but a good defender. It is a matter of emphasis.
