NBA All-Star forward Jimmy Butler has turned down a four-year contract-extension of about 110 million US dollars from the Minnesota Timberwolves, the team’s owner Glen Taylor told ESPN’s Darren Wolfson on Friday.

Having signed a five-year 87-million-dollar contract with the Chicago Bulls in 2015, Butler was traded to the Timberwolves in 2017. He still had two years left with his contract, but could choose to opt out in 2019 summer to become a free agent.

In the past 2017-18 season, Butler played 59 games and averaged 22.2 points, 5.2 rebounds, 4.9 assists and two steals per game. His performances has also helped Minnesota win 47 games and make it to the playoffs after 14 years.

The Timberwolves wanted to keep the iron-blood forward and thus made the offer, which he thought was not sincere enough. The team gave Andrew Wiggins a five-year contract worth 148 million dollars last summer and, according to Michael Scotto from The Athletic, negotiated with their center Karl Anthony Towns over a five-year contract for 188 million dollars. Both Wiggins and Towns were blamed for not doing enough in the playoffs while Butler could end up being paid less than them.

It’s not only money that Butler was not happy with. According to Sean Deveney from Sporting News, Butler took issue with Wiggins’ “work ethic and his approach on the defensive end of the floor.” He was not alone. Deveney said that both the team’s owner Taylor and head coach Tom Thibodeau had the same concerns over the 23-year-old young man.

Cycle's Thomas Duffy wrote on Twitter that Butler liked an Instagram comment saying that he and Kyrie Irving should play together for the New York Knicks in 2019. Interestingly, ESPN’s Chris Forsberg posted in June that Irving turned down a contract extension from the Boston Celtics and he could also choose to opt out his contract next summer.
