Jalen Brunson watched the ball trickle out of bounds Monday night. In the mind of New York’s starting point guard, as 22.1 seconds remained during the Knicks’ opening-game win of the second round against the Pacers, Brunson had dribbled quite obviously off Andrew Nembhard’s left sneaker. So when the officials agreed with Indiana’s bench, all pointing in the direction of the Pacers’ possession, Brunson did what any player in his position is now wont to do: He twirled his finger, imploring New York’s coaches to challenge the call.
