Every pitcher would be better off pitching in hte NL than the AL.
As for Zito to the Yanks...you know what? I'd rather have him than Randy Johnson, that's for sure. It aint like Johnson came to NY and thrived on the pressure. If the Yanks go for Zito, will they overpay? Most certainly, but, then again, look at what Meche and Lee and Drew and Soriano, etc, are getting...everyone's "overpaid". I'd rather overpay the younger guy who has actually pitched well lately and who WANTS to come to NY, as opposed to the surly, chornically in back pain older player who cannot stand playing in NY.
