Why can't sports commentators get poor Dirk Nowitski's name right?

It's "No-VIT-ski," not "No-WIT-ski." Just because there's a "W" in the middle of the name doesn't mean he's not German, and therefore pronounces it like a German - with the "W" pronounced as a "V." I have heard him say it, so I know it's right. Why don't people who talk about sports on television know? Can't they ask him?
