If this is this case, LP must put your best matchup(s) in the post regardless of position and if those players are perimeter players, having bigs that can pass the ball inside from the perimeter are necessary. Does it really work this way?
Bigs that can pass and handle increase the offensive flow, making the offense work at its best. From what I've seen with my team, the guards that have higher JS/JR take almost twice as many jumpers and threes than they do inside shots and drives. The other guards with lower JR or JS/JR take more drives and inside shots than they do jumpers and threes.
On the other hand, my bigs fluctuate between drives/inside shots and jumpers/threes. Some have close amounts with both categories, while others have a considerably higher amount of drives and inside shots. My SFs are close to equal with both categories.
Three of my players, for example:
SG- 11 JS, 10 JR, 9 DR, 9 PA, 4 IS. Shooting 16-50 from three.
PF - 9 JS, 4 JR, 7 DR, 7 PA, and 10 IS. Shooting 2-11 from three.
C - 8 JS, 5 JR, 6 DR, 4PA and 10 IS. Shooting 7-18 from three.
I hope this answers your question.
