The Chicago Bulls made history on Saturday night, and not for the right reasons. The Bulls suffered their worst loss in franchise history in a 56-point thumping at the hands of the Boston Celtics.

After the game mercifully finished, new Bulls coach Jim Boylen was clearly frustrated with his starting unit's play and sent a message to them in the post-game press conference, per Tom Webber of Sporting News:

“I think your play is embarrassing. Me subbing them is saving them, maybe. Maybe we saved them. The pro player thing, this is basketball; this is about honoring the game and doing the right things. Embarrassment is not giving the effort in that Bulls uniform, so I put five guys in that I thought could put the effort in.”

With the Celtics coming out of the gates with a 13-0 lead, Boylen, who replaced Fred Hoiberg last Monday, clearly had enough of his starting five's effort. He quickly pulled the plug on them and subbed in the entire second unit after five minutes of play. He did the same thing just three minutes into the second half. None of the starters saw court time after that.

This embarrassing loss for Chicago comes on the heels of a huge 114-112 victory over the Oklahoma City Thunder the night before. But for some reason, the Bulls started off on the wrong foot and ultimately just fell flat throughout the game.

Undrafted prospect Shaquille Harrison came off the bench to score a career-high 20 points in 29 minutes, as he led the backup troopers on a night when Boylen had a quick hook on his starters.

Chicago will get a chance to redeem themselves from this abysmal defeat when they host the Sacramento Kings on Monday.
