Upgrade close shot, forcing dip and standing dunk - you will have 7 finishing badges. Will equip big man contact dunks. Shooting - 3pt, mid range, free throw. Should be 14 - sufficient to be able to green everything. Playmaking - that is all up to you. If you'd like really Davis, you are able to go with post motions. I'd personally go for pass precision and ball handling, and add a small bit to article moves to have 5 playmaking badges.
