Barring a major trade, the Miami Heat will enter next season with largely the same roster as 2017-18, which means internal development will be paramount. Luckily, the Heat sport a trio of promising young players in Josh Richardson, Bam Adebayo, and Justise Winslow. Their potential isn’t just theoretical either, the “mini-three” are already amongst the Heat’s best performers. The trio, plus Wayne Ellington and Kelly Olynyk, posted a +19 net rating together, which ranked as Miami’s third best lineup in 2017-18 (with at least 50 minutes of court time).
