From No. 1 overall pick to trade piece in less than a month, Andrew Wiggins was given a crash course this offseason on the cold and calculating inner workings of the professional basketball world. With the NBA season finally underway, now it's time for class to take place on the court.

Minnesota's 106-105 loss to Chicago on Saturday provided the first valuable lesson for the 19-year-old. Wiggins was guarding Bulls swingman Jimmy Butler with the Timberwolves up 105-104 with 2.9 seconds left. Butler got the ball from an inbounds pass, took a dribble, and pump-faked. Wiggins bit hard, crashing into Butler and sending him to the free-throw line with 0.2 seconds on the clock. Butler sank both shots and the Timberwolves suffered a devastating defeat with their prized rookie making a rookie mistake.

"That play went by fast. I don't know what I was thinking," Wiggins said after the game. "A good play by a veteran player and a learning experience for me. I could have changed the outcome of the game. ... It hurt."

There are sure to be more learning experiences like that one coming Wiggins' way. Through his first three games he's been aggressive on the defensive end, too aggressive at times like he was against Butler, and he's yet to have a standout offensive performance.

Wiggins scored six points in his regular season debut, a 105-101 loss to Memphis on Wednesday. He had eight points in a 97-91 win over Detroit the following night, all eight points coming during an impressive attacking spurt in the third quarter, and eight more in the loss to Chicago. He's shooting 37.5% from the field.

This is what his season will be. There will be more mistakes made and more flashes of brilliance to come from Wiggins. His journey is just beginning.
