The 105-87 loss to the Boston Celtics on Monday was one game that 76ers coach Brett Brown quickly wants to forget.

"Last night for me was the most disappointing home game that we've had in a while," Brown said Tuesday after practice. "For the first time, I didn't recognize us. That's not this team at all."

The Sixers (2-22) shot 35.5 percent from the field and 14.3 percent on three-pointers. They committed 23 turnovers. They are mentally and physically fatigued.

"But like we remind them all the time, the NBA isn't for everybody," Brown said. "The NBA is grueling."

The grind of the league's schedule "is so unforgiving," said Brown, who acknowledged that most of his young players don't have a clue about how hard life in the NBA is.

"I feel like my job is to educate them . . . to first admit it," Brown said. "Second of all, we've got to put our big-boy pants on and let's get going.

"That's just life in the league. Maybe it's not for everybody."
