After getting dominated by the Hawks in Game 3, the Boston Celtics look to showcase the lessons learned from last year's NBA Finals run by bringing a higher level of urgency in Sunday's matchup. With the potential for the move-up of the conference semifinals, it is in Boston's best interest to finish off the Hawks quickly. They couldn't corral the desperate Hawks team in Game 3, who proved that they can make things interesting with their offensive firepower and relentless desire to collect offensive rebounds. The Celtics played from behind for much of the game and failed to get over the hump with Atlanta responding to every second-half charge. Drawing more from their superstars, particularly Jayson Tatum, and fully locking in their defense will be essential to their success in Game 4. However, the Celtics might also be without starting point guard Marcus Smart, as he is listed as questionable due to a lower back contusion. Dejounte Murray has been playing at a high level for the Hawks and making the biggest impact by creating opportunities for his teammates. Will the Celtics bring the necessary urgency against a determined Hawks team in Game 4?
