The Warriors haven't allowed James Wiseman to develop properly, he was meant to be their starting center but injuries derailed that.
If Wiseman was on any other team he'd be starting and would likely be playing much better
.
Obviously as of now Draymond is more important to the team but Wiseman was projected to be their star center but it seems like he might not be on their roster going forward in the next few seasons as it seems like he doesn't fit in team's scheme.
The Warriors have prioritized too many players (Steph, Klay, Dray, Poole, Wiggins, etc) to really invest in Wiseman so he's just sitting there collecting dust coming off the bench for a measly 10 minutes or so.
