Press X to Win might be my favorite phrase of all-time....no seriously [emoji23]
The play below is a perfect example of an instance where the help defender (Embiid here) could draw a charge. Obviously Embiid's contesting tendency would be high but perhaps every once in awhile........that said, guys like Lowry and Ilyasova would absolutely go into stationary Hands Up and draw fouls in situations like these.
Redick is already moving so "holding" Hands Up would trigger easy blocking foul (we dont want a cheesy way to create offensive fouls) But pointing the R-stick at Green would initiate a shot contest.
