how does this make sense?

Because of American Gladiators' current failure, NBC is doing a little damage control.

By scheduling a half hour episode of Dateline?....

Monday, June 9
8:00/7:00c - "American Gladiators"
9:00/8:00c - "Nashville Star" (Two-Hour Season Premiere)

Monday, June 16
8:00/7:00c - "American Gladiators"
9:00/8:00c - "Nashville Star" (90-Minute Episode)
10:30/9:30c - "Dateline NBC" (30-Minute Episode)

Mondays (as of June 23)
8:00/7:00c - "American Gladiators"
9:00/8:00c - "Nashville Star"
10:00/9:00c - "Dateline NBC"

Wow. They have no clue what they are doing.
