Tyler Johnson is making $5,821,260 this season. Next season, he'll be due $19,245,370. It's an exponential jump, courtesy of Nets' GM Sean Marks (Johnson accepted the Nets’ offer sheet in 2016) and will definitely cause cap issues. Don't get me wrong though, Johnson is an athletic and prolific basketball player. Given the right circumstances he's an amazing talent and huge help to the Heat. But right now, his role is ambiguous.
Last season, Tyler Johnson averaged 13.7 points, 4 rebounds and 3.2 assists. In nearly 30 minutes per game, Johnson was a beast.
