So I was watching the Spurs-Lakers game and Reggie Miller was talking about how Tim Duncan was in great shape, having one of his best seasons and that he had been back in the pool.
I knew he grew up a swimmer but apparently he was really good until a hurricane destroyed the one pool at his home in the Virgin Islands and so he had to quit around age 13.
I wasn't able to find anything more than that so would be interested in hearing more.
