Yep, Sinners is way-off base with this one. KB's dominance in the 80s finals series has never been repeated.
I only saw the later post-1980 KB live and yeah, he was a great little opportunist forward - sad I never saw him as a champion on-baller who would kick a lazy 5 goals a game as well.
This page has a great summary of his achievements -

5 goals or more 22 times in his career. Won our B&F award 5 times. Won our goalkicking award 5 times (including 1983 which I'd forgotten about). Most finals played, 59 finals goals (second to Titus). And all this as a midget rover/half forward flanker.
Heaps more accolades I left out.
