You could argue that a better question would be did NBC make a mistake cancelling Password Plus, Blockbusters, and Battlestars to try to save The Doctors and Texas? Both soaps were seriously flagging in the ratings by 1982 and the 3 games were holding their own by NBC standards. They did revive all 3 over the following years, to mixed results.
If i was doing a mock schedule, i'd drop
Texas, and keep
The Doctors and
Blockbusters. Now where does
The Doctors go, without the noon news issue? Keep it at 12:30, or maybe move it to 11am? As far as BB, i'd keep it at 10:30 or pair it with
The Doctors.( i know; putting a soap and a game back to back would be interesting scheduling by NBC, if it ever came to that). But if NBC is trying to save
The Doctors, you really cant do it opposite the TPIR juggernaut.
