"There is marquee rules that let players like Bogut salary be worth 100g. "
$100,000 is not and never was the marquee threshold.
The original marquee player rule, when introduced, said that the first $150,000 of the first marquee player's salary only would count towards salary cap for luxury tax purposes. For the second marquee player, that was raised to $200,000; to $250,000 for the third marquee player; and to $300,000 for the fourth marquee player.
Those rules also said that for each marquee player after the first, the number of restricted players (imports) allowed for the team would reduce by one. i.e., "Any team may replace any one or more of its restricted player entitlements with an additional
non-restricted marquee player". (NBL media release, 30 March 2016)
When Bogut signed, it was reported (The Daily Telegraph, 24 April 2018) as "$160,000 of this deal will count on the Kings' salary cap, which is part of the NBL’s local marquee signing set-up." So the marquee threshold has been raised over time, presumably as the salary cap has increased.
Does anyone know if the rule that the second and additional marquee players replace imports has been dropped or otherwise changed? If not, then Bogut is the Kings' only marquee signing.
It's also worth noting that the original rule changes stated that a contract review panel would set notional salaries for every player on a team and those would be used to determine the team's salary bill, for cap purposes. There's no guarantee those notional salaries bear any resemblance to the actual amounts paid to players. According to Aussie Hoopla (http://www.aussiehoopla.com/nbl-free-agent-tracker/), that part of the salary cap regulations is still in place.
