Yes but just because he's a better short blocker doesn't mean he's a better defender. He does still have room for improvement on other aspects of his defense as well as his offense generally.
I actually noticed that he got less blocks the better he played defensively and on the boards. It's like a CB that takes too many chances and racks up a ton of INTs...it doesn't mean that he is playing better than guys that only have a few picks. It usually means the are more reckless.
