The Butler did it.
The 28-year-old is under contract for $20.5 million for 2018-19 and has a player option at $19.8 million for 2019-20 - likely less than he stands to make if he declines his option and re-signs on a long-term deal.
Butler and his camp were reportedly appreciative of the Timberwolves' offer, but are electing to wait until next summer, when a rising salary cap and other factors increase the possibility of a larger contract.
Butler blossomed into one of the league's top two-way talents over his first six seasons with the Chicago Bulls before being traded to Minnesota last summer. In his first season with the Timberwolves, the four-time All-Star averaged 22.2 points, 5.3 rebounds, 4.9 assists, and two steals per game, playing a pivotal role in the team reaching the postseason for the first time since 2004.
