The Boston Celtics are in the NBA Finals for the first time since 2010, but one fan had enough faith in his hometown team to make a bold – and permanent – prediction long before the playoffs began. 

Jack Bienvenue, an 18-year-old from Wellfleet, Massachusetts, did the unthinkable when he got a Celtics 2022 World Champions tattoo on his arm. 

The bold part? He got it in March. 

"It was March 21st, the exact day. We were on a winning streak of 10 games, I guess. We were rolling a bit," Bienvenue said, via ESPN.

"It seemed like we were finally getting the pieces together. We were finally putting the puzzle together, and I thought it seemed like [a title] was destined to happen. That this team would make a historical run to the Finals, which they have, and just gotta finish the job. We got four more to win."
