The Boston Celtics and Brad Stevens are now on the brink of elimination after losing 113-101 in Game 4 of their Eastern Conference semifinal series against the Milwaukee Bucks.

With the Bucks now leading the series 3-1, the Celtics will need to win the next three games in order for them to stay alive in the playoffs, something that seems impossible considering they have lost the last three contests after winning the series opener.

After the game, Celtics head coach Brad Stevens told reporters that although they didn't want to be in thi position, he loves the challenge of going back to Milwaukee and winning Game 5 on Wednesday to force the series back to Boston on Friday.

“It's win or go home. You do the things you've been doing all along, you play the next possession to win it, and that's it, you focus on that. It takes a lot of mental fortitude, it takes a lot of mental toughness, and it reveals a lot. And so, you know, I'm looking forward to that challenge. We don't want to be in this position, but we are, and we've got to go to Milwaukee and do everything we can to give ourselves a chance to play here [Boston] friday night.”

There's only one player on the Celtics' roster who has come back from a 3-1 deficit, and that is Kyrie Irving. However, he does not have another superstar beside him — certainly not LeBron James. The rest of his teammates will need to double or triple their efforts if they want to have a shot at winning the last three games and turning around this season for Brad Stevens.

It's something that seems impossible at the moment, and maybe it is already, but the Celtics and Brad Stevens will need to regroup and remind themselves what they've worked hard for all season long: the chance to win a championship.
