Being a well-off pro athlete doesn't mean you're immune to emotional issues; we saw a number of hockey "enforcers" do themselves in last summer.
The news today has KC Chiefs linebacker Jovan Belcher committing suicide in the Arrowhead Stadium parking lot after killing the mother of his child earlier this morning. Were it a less somber and tragic moment, you'd call this Belcher move a brain burp.
Instead, you've got a child who is instantly a orphan and a Chiefs coaching staff who witnessed a snuff film the day before a game; Belcher reportedly thanked head coach Romeo Crennel for all he had done before ending his life.
The NFL is planning on having Sunday's game against Carolina go foward, but when neither team is in the playoff hunt, one could easily see the teams pass on playing.
The Chiefs have had a lousy year, going 1-10 so far. This makes the problems on the field pale by comparison.
