In my style someone would get laughed off the mat if they said that someone who has never sparred could submit someone who sparred constantly. I find it interesting that other styles actually believe such a thing is possible.
This has been covered. You keep assuming the discussion is whether someone can beat someone else in competition if one spars and the doesn't. That has never been the discussion. Seld-defense training comes in many types and levels. Some can be had with zero sparring. Adding sparring likely raises the level of effectiveness, as does any number of other factors.
