Bradley: Celtics look defeated, 'have to stay together'

The NBA playoffs have been a nightmare so far for the Boston Celtics. Now facing the unenviable challenge of going on the road down 0-2 to the Chicago Bulls, the Celtics need better body language, according to guard Avery Bradley.

"I looked around and, a few times in (Game 2), guys were putting their heads down, I think getting down on themselves," Bradley told ESPN's Chris Forsberg. "As a team we have to stay together."

Perhaps even more disturbing is Bradley's statement that he thinks the Bulls can smell blood.

"I could even hear (Rajon) Rondo like, 'Yeah, they gave up. They gave up,'" he said. "But you can never let a team see that."

At this point, history is working against the Celtics. In addition to Boston becoming the first No. 1 seed to fall behind 0-2 in a best-of-seven first-round series, only 18 teams in the 70-year history of the NBA have come back from such a deficit to a win a series.
