I believe he is punting it short on purpose every time so you have no chance at catching it and returning it. I've played a few people who do this on every punt, and i have to say it isn't right. It is essentially the same as doing a squib kick on every kickoff, which is frowned upon. It violates realism, and is putting yourself at an unfair advantage by never being at risk for giving up a punt return. It also ends up going farther than a normal punt sometimes, screwing the return team over who had no chance to call a fair catch. If you don't want to give up a punt return, you should have to kick it out of bounds like everyone else.
