exactly, since it has not happened it is at this current time conjured, not yet fact. we are not talking about the likely hood for something to happen we are talking about what if something happens.
the only possible answers to your question are hypothetical answers, until your "if" statement actually happens then it is no longer hypothetical because we have facts on what would actually happen. The only possible non hypothetical answer to your question would be if steph was an NTer, read your post, went out to shoot 80 times in a NBA basketball game, and replied to your quote with "That."
there is nothing in the definition of hypothetical or hypothesis that suggests that the subject of the claim needs to be impossible.
"what would you do if you won the lottery" is a hypothetical question, any response to it would be a hypothetical answer unless the person had actually won the lottery and was detailing events that actually happened.
your question is no different than someone saying "steph would be the GOAT if he wins 7 championships"
Not every created situation is a hypothetical; not every if is a hypothetical.
But I'm the bad guy for continuing, so let me stop.
the very concept of a hypothesis is based around possibilities and not impossibilities
yes those two things are not the same, but they are both hypotheticals.
so I ask again, where in the definition of a hypothetical or hypothesis does it disqualify a question which can happen but at this moment in time there is no way of providing a non hypothetical answer?
all created situations are by definition hypothetical, they are an educated guess of what would happen if all proposed factors come into play.
