Tyler Herro
After being at the center of rumors upon rumors again this trade season, Herro needs to show the Heat front office he can be a legitimate cornerstone for the franchise.
Despite being a proven 20-point-per-game scorer, there are questions about whether Herro can be more than a sixth-man-type scorer. Training camp allows him to prove he can take things up another notch, especially as a playmaker and defensively, and prove to the Heat that he's worth building around.
One of the main critiques of his game is his defense. In a Heat culture steeped in grit, effort, and two-way play, Herro will have to prove himself on the less glamorous end if he wants to be a lock as a starter or high-usage bench scorer. Opposing offenses have picked on him throughout his career so far, and training camp will be very important in showing he can be more cognizant and physical on that end to not be a real liability in the Heat's switch-heavy scheme.
Now in his sixth season, Herro's days of being a young up-and-comer are behind him, and he's now expected to be one of the leaders. With veterans like Jimmy Butler aging, the development of Herro into a vocal leader and on-court presence is so important. The Heat will look for him to not only perform at an All-Star level but also take some leadership with younger players and set the tone for the culture of the team.
