Sometimes I leave a locker room pretty happy with what was said about the team or the upcoming opponent. Sometimes the comments are so clich ridden it's amusing. Just like in any group of people, some are smarter than others, some speak more eloquently than others, some welcome the spotlight, while others shun it. Some coaches put a muzzle on their players. Jim Fassel of the Giants hasn't let his team speak in anything but generalities since the middle of November.
Some players close themselves out from the media completely.
I've always thought that was irresponsible. Aaron Beasley decided early in his career he didn't like being criticized in print. He stopped talking to the media for a while, but since has relented and is a very good and thoughtful interview. Part of being a professional athlete is dealing with the public, including the media. If you think a writer has been unfair, close him out.
