Well, doing sanshou doesn't necessarily mean you won't get an adrenaline rush or be pi.ssed off, but if you don't train to develop those skills you mentioned, then of course you won't worry about them in a real fight--you won't have them.
That's my complaint with saying that sanshou isn't very important because you won't think about using those skills (distance, timing, etc.) in a real confrontation. If you don't practice those skills in sanshou, d a m n straight you won't be thinking about them in a real fight.
