I think that the media has been too hard on Herschel [Tzvi] Walker.
A] He obviously holds like the Shitah of the Sheiltos [against pashut pshat in the Gemara in Sanhedrin] that Bnei Noach are commanded in Pru Urivu.
B] Plus, he likes to spread his love to as many people as possible.
C] Also, let's face it. In the world of sports [and not only], a large percentage of athletes have random offspring that emerge from non-committed relationships [not to justify it but that is what happens when uncurbed, unchecked, unbridled tyvah combine with a complete lack of sense of responsibility and morals]. A special mazel tov to Latrell Sprewell, who had three children by three women before he turned 21. Only Chasidim have that many kids at that age - but by one woman.... I guess Latry wanted to ease the burden.
