The Miami Heat tipped off their 2026-27 preseason with a shows of new talent, as several rookies logged valuable minutes in a matchup against the Toronto Raptors on October 3. While Giannis Antetokounmpo's debut for Miami grabbed headlines, the team's first-year players provided a glimpse into the future. The Heat are coming off a 143-117 win over the Atlanta Hawks on April 12, part of a recent 3W-2L run that includes two straight victories.
Four Miami Heat rookies saw action in the preseason opener. Undrafted free agent Ian Schieffelin was the standout, scoring 11 points on a perfect 4-of-4 shooting from the field in just 10 minutes. He also hit his only three-point attempt and both free throws, adding three rebounds and an assist. Second-round pick Ryan Conwell, selected 37th contributed six points and two assists.
Tre Donaldson, a two-way signee, tallied six points and three assists. J'Vonne Hadley, another undrafted player, made the most of his limited time with two points and six rebounds. Their performances offer early data points as the team evaluates its depth chart ahead of the regular season.
This preseason game was the first look at a revamped Heat roster following a massive offseason. The acquisition of two-time MVP Giannis Antetokounmpo dominated summer discussions, and his presence on the court shifted the entire dynamic of the team. Toronto, featuring a returning Kawhi Leonard who did not play in this game, also made significant moves.
The contest allowed coach Erik Spoelstra to experiment with rotations and assess how new pieces fit. For the rookies, it was a critical first test against NBA competition. Every minute on the floor is a chance to earn a spot in the rotation or secure their place on the roster.
Miami's success has often been built on finding and developing undervalued talent. The impressive play from undrafted players like Schieffelin continues that tradition. His efficient scoring and energy could help fill a role off the bench. Conwell's playmaking and Donaldson's defensive activity (a steal and a block) show different skills the coaching staff can develop.
With a core now built around Antetokounmpo, having reliable, low-cost contributors on rookie contracts is vital for maintaining roster flexibility. Strong preseason performances can build trust and lead to more opportunities when the games count.

The preseason opener is just the first step. Miami will use the next several games to fine-tune its systems and solidify its rotation before the regular season begins. The rookies will need to show consistency and an ability to adapt as opponents game-plan more seriously.
Building on their current two-game winning streak from last season's finale, the Heat aim to carry positive momentum forward. Integrating a superstar like Antetokounmpo while cultivating young talent is the dual challenge. How these rookies develop could be a key subplot to Miami's championship aspirations this year.
