The Andre Drummond and Reggie Jackson pick-and-roll is a dangerous thing. Stick too closely to Reggie Jackson and you'll give up an ally oop to Drummond. Try and keep a body on Drummond and Jackson can kill you with a layup or a floater. Even when you have three defenders dedicated into forcing a Jackson miss, well you've just opened up the lane for a trailing Drummond to do this. Ouch.
