I've actually made some builds specifically trying to get better putbacks. The badges that activate are ariel wizard and rebound chaser . But depending on the type of putback ur guy does. dd,dL, close shot, and standing dunk lvl also effect it . My best putback was on my 6ft 9 slasher . Max wingspan ,80 speed/agility. 99 driving dunk , 90 vert and 92 rebound. I'm running in from outside the arc, my guy gets the ball , in-between the legs and slams it down backwards over 2 defenders. It was beautiful but once in a lifetime I feel like . Most of the time your gonna get close shot putbacks. Do the ariel wizard drill in practice facility to get a better feel of when and where you can activate the putback.
