I know what it's for. But yanks like to recite such statistics as though they are in any way meaningful as anything other than tracking potential in recruits. It's a bit like someone saying that Cristiano Ronaldo is the world's best athletes because he can do a hundred keepy-uppies in a row or because if he tries his bestest he can kick the ball through the air for 90 yards.
