The acquisition of James Harden and Blake Griffin on deadline day resulted in the Nets having a super team.Another factor that plays into the Brooklyn Nets' strengths is the depth of their squad. For a team that was ravaged by injuries at one point, they managed to secure victories with the contributions of Landry Shamet and Jeff Green.Saturday’s game was the first time the superstar trio of Kevin Durant, James Harden and Kyrie Irving played together since Durant hurt his hamstring on Feb. 13 against the Warriors. @krisplashed https://t.co/3XbsgZJcnR— NY Daily News Sports (@NYDNSports) May 15, 2021Moreover, Harden, Kevin Durant and Irving are a formidable power trio that has not been seen in the NBA since the Dwayne Wade, LeBron James and Chris Bosh era.Boston Celtics' strengths heading into the playoffsJayson Tatum #0 and Kemba Walker #8 of the Boston CelticsJayson Tatum is having the best season of his career, which is good news for the Boston Celtics. His partnership with Kemba Walker has been great for the Celtics. Tatum recorded 50 points, while Walker recorded 29 points to help the team overcome the Washington Wizards in the play-in tournament.The Boston Celtics are also a decent defensive team, as they finished the regular season ranked 14th in defensive rating (112.5).Brooklyn Nets' weaknesses heading into the playoffsThe Brooklyn Nets have a practically non-existent defense. Despite being one of the worst defensive teams in the playoffs, they have managed to outscore their opponents.Staying healthy has also been a challenge for the team, as the Nets reserves were called upon more often than expected.Injuries have prevented the Brooklyn Nets power trio from playing together and building much-needed chemistry.Boston Celtics' weaknesses heading into the playoffsThe Boston Celtics offense relies largely on Jayson Tatum, and this could be a serious problem for the team. An off day for Tatum could lead to a complete breakdown of the Celtics offense.The Boston Celtics will also play the series without their second-leading scorer, Jaylen Brown, who is out for the season with a wrist injury.Squad depth is not an area the Boston Celtics boast as bench production has been terrible this season. The reserves are relied upon to keep their team in the game while the starters rest. However, not enough quality comes from their reserves when called upon.Brooklyn Nets vs Boston Celtics Series PredictionThe Boston Celtics have orchestrated upsets in past playoffs and could pull it off against the Brooklyn Nets. However, with the limit offensive firepower available to the Celtics, it will be a difficult ask down the stretch.The Brooklyn Nets are the favorites to win the series as they have the better team on paper. Regardless, the Nets have to stay focused throughout to overcome the Celtics.
