Green times any shot, but a good jumpshot gives it a wider green window. A bad one still works — you're just making it harder.
Use a fast, straight release. Straight jumpers have the widest green windows and least timing variation:
Prioritize shooting attributes. 90+ three-point gives the best green windows. Don't sacrifice shooting for dunk packages. After creating your build, use the Build Selector in the mod menu — guards, wings, and centers have different shot speeds and the script needs to know which you're running.
If you're bricking and your values are at 3, the problem is almost always your jumpshot. A slow or hitchy release gives the AI a tiny green window to work with. Switch to one of the recommended bases above and the difference is immediate.
