I was just watching the special features on the Street Hawk DVD and they where talking about how the Street Hawk series was specifically made to run in the Monday night 8pm slot for ABC, but at the last minute the show was pushed to Friday nights 9pm slot and the Monday slot was filled with MacGyver.
They gave some interesting information about the Monday time slot saying that anyone in that time slot was guaranteed at least a 3 year run because of the way it works with the Monday night football.
I thought it was interesting to hear which show was pegged to be where MacGyver ended up being. Although I must say I find it more than a little disconcerting that a 1 season show gets a bunch of special features including the main cast reminiscing about the show and even talking about how they wouldn't' mind reviving it, while the 7 season MacGyver gets nothing.
