There was NO descriptor "unproven" in the question.
"Do you think it's a good thing for a program to stick with a coach had back to back losing seasons?"
Highlight the part that talks about "proven", "unproven" or "long term success".
Hence, the "it depends" answer, since all questions can't be answered by a simple yes or no. And that's why you see the goalpost move in the responses.
Like I said. Arguing semantics. Pathetically stupid as usual.
Can we end the stupidity if Watson comes back and makes the same statement without that big bad word "unproven' that's making you cry like such a big baby?
