Yet the 2 players that's supposed to work wonderfully together Zion/Trey, shows up with a +3.8 net rating. BI/Trey is a +8.0 net rating. This is why when you post stats like that, context is important.
Ingram, despite playing 6 fewer games, shows up more in the top 50 net ratings for this team than Zion does. So perhaps we need to realize that Zion just didn't have a great year last year and most comps including his name are going to be worse. That's where the improvement needs to come from. No matter if Ingram stays or goes.
