People do funny things. Sometimes they work hard all their lives and achieve exactly what they have been striving for, then they walk away. A nation of skin watchers is left to wonder, "Geez, why did Sherry Stringfield show her great ass in a series of great quick shots on NYPD Blue way back in 1993 and then basically pull a disappearing act? Why did she remove from us the strong, compassionate sensuality of her face and the hope of seeing her breasts, more of her ass, and maybe even her bush?" There is no answer for such questions. After only one year at NYPD Blue, portraying David Caruso's ex-wife, Stringfield opted out of her contract. After two seasons on ER, she ditched that gig. In 2001 she negotiated a deal to return to ER for three more terms. Women. Don't ever try to figure what makes them tick.
