After playing for one season at UNLV, Jones was forced into declaring for the draft. He was ruled ineligible because his ACT score was thrown out.

In 30 games as a freshman at UNLV, Jones averaged 11.5 points, 4.5 rebounds, 1.4 blocks and 0.9 steals.

Jones signed by the Suns in September and ironically made his NBA debut in November against his hometown Sixers. He's only played for about 20 total minutes in six NBA games.

Jones will compete against Aaron Gordon, DeAndre Jordan, and Glenn Robinson III in the dunk contest on Saturday night.

The 6'7" high-flying lefty was showing off some of his stuff in warmups on Monday.
