Unlike any other position, Centers like him need to have more conditioning and just need to focus on improving himself rather than chasing the title because obviously, he is not like Lebron in his rookie year because he can take the risk without putting his physical health on the table. Unlike Wemby, he doesn't have that option, he needs to take it slowly but surely to scope and absorb all of that experience to be a dominating player by the next years of his NBA era.
Wemby has the talent of an ideal big man, could shot outside and has a good range in mid range. However, there's one thing that he need to develop, and that is his physique. I mean we can understand that since he is still young, but since he's in the NBA now (his ultimate dream), it should not be a problem from a team on transforming Wemby to be like a Giannis body. Let's just wait and see, maybe a season or two, we will see a more competitive Wemby.
Maybe he need to gain weight a little bit but not to much since if he let his weight became more bigger for sure he will be injury prone with that since 7'4 for sure he's body can't handle much more bigger weight and it can affect since performance since for sure with that he became more slower. What he need to develop is his confidence since he really need that plus a good teammates surround him so that he can get more better plays and make sure he also can get help if he need his teammates to perform well.
For now can't expect anything explosive to them also with young Spurs but if this team will get a lot of experience or get a some veterans to guide them maybe things will be change and they can get a lot of wins next season.
