New Chicago Bulls head coach Jim Boylen made bold moves in the team's embarrassing 133-77 home loss against the Boston Celtics on Saturday night. After seeing lackluster effort from his starters in the first five minutes of the game, Boylen immediately pulled his entire starting five and subbed in his second unit. In the second half, he also opted to sit his starters for the final 21 minutes of the game.

Just three games into his first head coaching job, Boylen is already putting his stamp on the young Bulls, and stressed his different coaching style from that of former coach Fred Hoiberg.

“I approach the locker room different than Fred,” Boylen said per ESPN. “It doesn't mean better, worse or whatever. We're different people.”

The long-time assistant coach refused to comment on reports that Hoiberg lost the locker room, and as a result lost his job in the process. He did, however, give a safe answer without taking any shots at his close friend.

Jim Boylen isn't the nice guy that Fred Hoiberg is. The young Bulls players probably got used to Hoiberg's lax coaching style. They won't get that from Boylen, who demands a lot of effort from his players. This isn't to say that Hoiberg didn't demand enough from his players, but Boylen is clearly more demonstrative than Hoiberg ever was for Chicago.

In fact, in his first week on the job, Boylen did not waste any time to make his mark on the Bulls' locker room by putting them through long and rugged practice sessions and extra rounds of shoot around. He further proved his worth with his disciplinary move during their atrocious loss to Boston.

This will be a long and hard season for the young Bulls. But perhaps, this is what they'll need to go through to get better as a team.
