Celtics coach Brad Stevens takes ‘Ice Bucket Challenge’

Nearly a week after point guard Rajon Rondo drenched himself in the name of ALS awareness, Celtics coach Brad Stevens followed suit Tuesday by taking the Ice Bucket Challenge.

Stevens, entering his second season in Boston, is one of the latest Boston sports figures to get soaked for charity.

The spread of the Ice Bucket Challenge has helped donations spike, said Barbara Newhouse, the ALS Association’s national president. In a 10-day period that ended last Thursday, donations reached about $160,000, compared with $14,480 in the same stretch last year.
