True, but there is a difference between the will/dedication it takes to get skill and the will/heart it takes spar and compete.

It's a continuum. If a guy with more heart that skill gets in with a more skilled guy with less heart, a guy who gets hesitant once you hit him hard, the less skilled guy can impose his will if the skill gap isn't too big and if the gap in will/heart is significant. If the guy is so much more skilled that the guy with tons of will, the will won't become a factor.
