In the NBA it's very hard to win a championship without an effective low-post scorer. You may have a guy who stretches the defense because of his ability to score in the low post along with a good mid-range jumper like Dirk Nowitzki (more recently) or Pau Gasol, or just an all-out monster in the post like Tim Duncan or Kevin Garnett.
It's the three-point shooters that bring down the house and the high-flying dunkers who bring up the noise in the arena.
Most recently, you saw the Memphis Grizzlies, who are stacked in the post with Zach Randolph and Marc Gasol, take down the No. 1-seeded San Antonio Spurs by playing stellar defense and pounding the ball down low.
Low-post play is the meat and potatoes of an offense, while your long-range shooting is the gravy. You can win without three-point shooters, but you would be hard-pressed to do the same without low-post guys.
To me, they are the most important players in the NBA, so I've delved into the NBA history books and pulled out the best low-post players of all time for your viewing pleasure.
