If the Knicks beat the Spurs in the finals they would be the first non-40⁄20 team to win a championship without beating a 40⁄20 team before the finals.
If you’re unfamiliar with the 40⁄20 rule, it’s Phil Jacksons formula for what makes a team a contender. A team must win 40 games before reaching 20 losses. This season The Spurs, Thunder, and Pistons are the only teams to reach the milestone. Only 4 teams the last 44 years have won it all without meeting this criteria, however there have been plenty of runner ups that have reached the finals while breaking the rule 5 of the last 6 runner ups have actually been outliers. The difference between the many outliers to reach the finals, and the ones that win the finals hinges on beating elite teams en route to the finals.
The Cavs upset the one 40-20 team in the east this year, allowing the Knicks to bypass the chance to test themselves before the finals, akin to the b2b finals runner up Nets in the early 2000s(we know how that turned out.
Side note; that Houston Rockets team was ridiculous.
