I'm not really a big NBA fan, but watched Pacers vs. Knicks last night due to lack of other choices.
Knicks were basically handed the game at the end... apparently almost everything is challengeable nowadays. One exception is a kicked ball. Late kicked ball call that obviously was not kicked upon replay, can't be challenged and Knicks hit a big basket instead of it being Pacers ball.
Also, Knicks fouled on a shot with a LOT of body, announcers were surprised that it was overturned on review and called a clean block.
Finally, on a questionable offensive foul called on a Pacers screen, announcers were surprised that they'd call that foul in the final minutes of a game. Pacers challenge failed.
