Sources said the Grizzlies voted against the new lottery reform solely because of the new rule disallowing a team from picking top 5 in 3 consecutive years. As @BobbyMarks42 says, the Grizzlies have the more favorable 2027 first-rounder of Cleveland, Minnesota and Utah, and because the Jazz again have a top-5 pick this year, their first in 2027 cannot be in the top-5 under new rules.
