Absolutely. That applies to a lot of sports though. I don't watch much sport that the BBC puts out, apart from MotD. That means I'm equally struggling and having to google some of the other people listed.Hence lots of folk won't have a clue who he is. (Is a public vote still the way this is chosen?)
Saying that, Littler has made national news and has broken out of being a purely Sky story. If anyone genuinely has not heard of him then you mustn't be following sport generally. Same way that I have not watched boxing for years but I know who Tyson Fury and Anthony Joshua are, I don't follow F1 but I know the Verstappen has dominated again. It's out there.
