For the first three games of this Pacers-Heat series, Indiana confounded Miami by having big center Roy Hibbert lay back on pick and rolls instead of aggressively challenging the ball-handler. LeBron James adjusted fine, but Dwyane Wade did not. In Game 4, the Heat responded by going away from Hibbert and instead running pick and rolls involving Pacers power forward David West.
The delay tactic is over, though, in Game 5. Early on, Miami has attacked Hibbert, and now, they're succeeding. James and Wade keep attacking aggressively off the pick and roll and have fooled Hibbert into committing too much to their drives.
This is concerning for the Pacers. Hibbert is big, but he's not getting any quicker.
