The NBA Draft is in full swing. So far, the top picks have gone as expected.

One major transaction, however, shocked NBA fans: Chicago traded star wingman Jimmy Butler to the Minnesota Timberwolves. It was the first #WojBomb of the night.

It makes a lot of sense—Butler returned to his former head coach in Chicago, Tom Thibodeau, who is Minnesota’s head coach and president of basketball operations.

The full deal: Jimmy Butler and the No. 16 pick went to Minnesota, and Zach LaVine, Kris Dunn, and the No. 7 pick went to Chicago.

Many were critical of the Timberwolves, claiming they did not get enough in return for Butler.

Butler, 27, has made three NBA All-Star Teams and was the league’s Most Improved Player in 2015. He made the All-NBA Third Team this season.
