2017 UPGRADE: Lob Pass Option = Guard to Guard pass, then RETURN PASS to intial ballhandler BEFORE passing to the wing. Dunk or Tip-in layup as EARLY OFFENSE because you end up trying too many 3-pointers with CHIN.
Most smart coaches know that CHIN is a Man-2-Man Offense, the best way to kill backdoor passes is to drop into a 2-3 Zone Defense & dare them to beat you with 3-pointers.
The problem I've always had with the flare screen is that the shooter rarely makes that shot because he gets no momentum into it. Just watch this video, the shooters make less than 10% on that shot. I've been to D1 practices of teams who run this and it is the same thing, the shot is not ma=de at a high %.
