I was stunned at the rate at which he scores when he reaches base. However, weren't some of you BP guys arguing that scoring runs is the product of those hitting behind the player in question? Is this only used when it's convenient for the argument?
If he's scoring at a high rate for when he reaches base, that's mostly due to luck. However, Nick runs the bases very well, he has good speed for a big guy, and is smart in his judgements. And, he's often starting on 2nd. But still, there's probably luck in the timing of hits behind him.
