It's intelligently written, and for the most part, holds one's attention. That's a lot to ask, nowadays! It raises interesting issues about drugs in sports, though I think it could explore them more deeply. Some plot elements strike me as pat and far-fetched. There's also a problem of consistency in tone in both dialogue and characterization. The swimmer, for example, is portrayed at times as the most inarticulate lunkhead on the planet, but when need be, he is able to express his thoughts quite well.
I found it superior to the playwright's previous effort, The Christians.
