Eh....if you're doing man on the street and someone notable walks by, you talk to them for sure. The only purpose is to generate interest and thus viewers.
Look, the reality is that a great many of these women aren't all that knowledgeable about the sports they cover. Some do (Pam Oliver is a very good reporter. Erin Andrews has improved drastically over the years.), some can at least fake their way through it, and some have no clue. The worst ever was probably Lisa Gurrero who clearly had ZERO idea about what she was talking about and eventually left sports reporting altogether to work for one of those hack shows like Inside Edition.
