After jumping out to a 2-0 lead in the best-of-seven first-round playoff series against the Boston Celtics, the Chicago Bulls were riding high and eyeing an improbably upset of the No. 1 seed.However, things quickly went south, as point guard Rajon Rondo injured his hand and the Bulls lost four straight games to the Celtics and are now eliminated from the postseason.It's been a tough stretch for the Bulls and, of course, for their fans, who watched as their favorite team was sent into offseason mode via a particularly disheartening 105-83 loss in Chicago on Friday night during which the Celtics were in control the entire game.As you can hear and see below, Chicago fans weren't happy with the blowout loss at the United Center, and started chanting "Fire Hoiberg!" at their embattled coach:

On the other bench, though, Boston coach Brad Stevens did not appreciate the chants. In the video below, cameras catch him shaking his head and mouthing "shut up" in response to the crowd's bashing of Hoiberg:

Though Hoiberg called out Boston's star player - point guard Isaiah Thomas - for carrying the ball earlier in this series, it's clear Stevens is still a Hoiberg supporter and doesn't want the Chicago coach to lose his job after a rough season.

After the game, Hoiberg told Yahoo! Sports that he understands why fans are upset and that he's upset with how the Bulls' season ended, too:

“It was a frustrating game, there’s no doubt about that,” Hoiberg said. “Again, the high note to start this series, the way we got out to a 2-0 lead, and we couldn’t finish it off.”

Though the season was frustrating for Hoiberg and the Bulls, the fact that they made the playoffs at all was a victory in itself. Chicago had to scratch and claw until the final day of the season to earn the No. 8 seed with a 41-41 record, barely edging out the Miami Heat, who also finished with an even.500 41-41 mark.

By bringing in Rondo and veteran guard Dwyane Wade before the season to play alongside star forward Jimmy Butler, the Bulls were hoping to have a better showing this year, but that core never really jelled until the first two games of the postseason.

Then, of course, Rondo's injury put an end to any sort of chemistry the trio had been building, so Hoiberg can't be blamed for that, per se.

As the 2017-18 season approaches, Hoiberg's job is probably safe. However, if the Bulls (who are sure to undergo another roster transformation this offseason) struggle to start next year, Hoiberg may feel his seat start to heat up.
