Also, in The Most Toys, Worf is the replacement OPS officer after Data is presumed to be dead.
True-- Troi called it a 'promotion' too, which would have put him right in the command track. In a way it makes sense since Worf was a bridge officer full time.
In some ways it doesn't, because early in the show it was stated Geordi had more experience.
Strangely, Geordi was the go-to guy if the top three were off the bridge during the first season.
Then after he got his two promotions, he wasn't left in command once AFIK-- it was either Worf or some other junior officer.
