The Slate article is excellent. I can't help but feel like the current Sportscenter shows are designed based on meticulous audience research conducted at frat houses. "The test audiences really like the catchphrases, so we must have 2 per highlight!" "The group went wild over that slam dunk, let's try to make sure that each segment has one dunk."
My biggest objection is the random organization of the show now. Used to be, each major sport was covered in its own segment. Now, they'll switch from NBA to MLB to some lame interview to 2 minutes of teases for highlights to come. It pretty much forces you to watch the whole thing, especially since my favorite teams NEVER seem to make the first segment.
