It's hard to get tired of watching the raw footage of this dunk, so when there's some fresh knew knowledge about Blake Griffin's smash on Kendrick Perkins, it's just a cherry on top. John Brenkus and ESPN's Sport Science segment took a look at the numbers behind Mr. Kia's jam. Here's the rundown: He used about 700 pounds of downforce, he extended his flight time about .10 seconds by pushing off Perkins, the ball went two feet above the rim, he dunked at an angular velocity of 900 degrees per second, and the ball got up to 40 mph going through the hoop. Got it? You'll be tested on this later.
