The Boston Celtics made up for their poor performance in Game 1 in brilliant fashion, picking up a very important win against the Miami Heat in Game 2 of the Eastern Conference Finals.

The Celtics were a well-oiled machine on the court, putting on a clinic on both ends of the court. There was much cause for celebration in the Celtics locker room, but not for Grant Williams.

In an adorable post-game video, Jayson Tatum took his sone Deuce to the locker room to give high-5s to everyone on the team. When Grant Williams entered the locker room, he did the same and tried to give one to Deuce.

Deuce and Tatum hilariously ignored Williams, leaving him with his hand out and in an awkward position. Grant laughed it off and walked away. One NBA fan on Reddit hilariously quipped that there is some bad blood in the Celtics locker room after Deuce snubbed Williams. 

Deuce has become a highlight during these Eastern Conference Finals. After Game 7 of the Celtics-Bucks series, Deuce joined his father Jayson at the post-game press conference.

One reporter asked Deuce what plans he had when he was in Miami, to which he adorably responded that he was going to go swimming when he would be in Miami.

Regardless of the snub, Williams and the Celtics will be thrilled with the work they put in last night. They overturned a 10-point deficit into a 25-point lead against the Heat during the first half of Game 2

The Celtics will be extremely confident heading back to Boston for Games 3 and 4, as they were able to pick up a win away from home. The Celtics will want to defend their home court during those games, as it would allow them to take a 3-1 lead over the Heat, and just 1 win away from reaching the NBA Finals for the first time since 2010.
