Many NBA players and so called stars view the defensive aspect of the game with disdain — not these guys. The flashy showmen, desperate for publicity and endorsement deals, need not apply for this list, which is all about defensive grit and toughness.
The following is a preseason power ranking of the top five players at each position based upon defense. This is not about potential and only takes into account what I believe to be true for next season.
Players who are expected to miss significant time next year due to injuries or those that whose health situations still lack clarity did not make the list. You cannot be considered a top five player in anything when you’re not playing the game.
As a bonus I have included an "On The Cusp" player, someone I believe has the potential to be regarded as a top five defender at their position by seasons end.
