Ok I decided to take a look at a few shooting charts for spacing, assuming Bagley starts next season, and Giles plays a decent amount of minutes too.
Here is Bagley's
As you can see heavy use in the key, also being a lefty, (an advantage on the block on one side too but low volume)
So for spacing purposes the left side of the chart beyond 3, same side elbow would be a good place to have our other big.
Now take a loot at Vucevic shot chart.
He is hot right where we want him at 3 pt depth to maximize spacing.
Take a look at Bjelica now
Also fantastic on that side of the floor.
Now when you look at Harry, who is a dangerous passer, he's not very efficient unless close to the basket.
So to me, Vucevic offensively looks to be the perfect balance with our bigs offensively. Not to mention a good rebounder.
Develop Swan or draft a bruiser second round to fill out roster or in case we need a brute for a couple of minutes vs Cousins or something like that.
