I'll point out my thirteen year old son as an example. He is 5'9" quick and has long arms. His strength as a defender is using his quickness and long arms to deny the ball, especially if he is defending the point guard, once that player gives it up. In tandem with his teammates, he can isolate the ball to one side of the floor, then to a quarter of the floor, then into a trap because the point guard has passed the ball to a lesser ball handler and can't get it back. That's how you cut the head off the snake defensively. He's worked on picking his spots to gamble and accordingly is staying on the floor longer.
You offered a good baseball analogy. The trick is convincing 20 home run guys that they're not power hitters and don't have to go for the downs 90% of their at bats. They will produce more offense in the long run by adding 40 points to their average and cutting their strikeouts in half. I was trying to point out that even Gioncarlo Stanton will strike out and fail to move a runner more than he will take a pitcher deep and that frequently kills innings. Just like a Locure type player gambling for the pocket pick will more often than not put his team in a lurch. In baseball, a smart pitcher will turn a batters overagressiveness against him and induce weak ground balls. Similarly in basketball, a smart point guard will use and opponents overagressiveness against him and foul him right off the floor. And while certain things can be taught, the smart pitcher, or player will win the battle more often than not.
