Senna is no great loss to Sky. I never thought he was that good. Seems Ch4 will be rotating people through the year. I suspect Murray will only be at the British GP for instance. I can't see him flying all over the world every fortnight.
Senna and Karun are easily, by a monumental margin, the best people along with too a lesser degree the Davidson the best technical people to talk during testing/the race weekend.
Senna/Karun constantly gave great insights during practice while Crofty/Ted now just mostly make up complete BS and largely get shut down by the more knowledgeable people.
Sky is losing all their technical people while increasing the nonsense factor. Screaming too complex any time a simple explanation is easy to do and interpreting every look by any driver as some massive statement on themselves, their team or their relationship to whoever happens to be stood near them.
Less technical people with a clue what they are talking about and a greater ratio of idiots like Crofty is extremely bad for the increasingly unwatchable Sky F1 shows.
C4, will have to see. They've got some good technical coverage people, Webber for some Aussie colour. Don't like Mackensie, glad Perry is gone, new presenter is a massive douche. Eddie is at times unbearable but knows too many people and gets, or at least is willing to dish our rumours before anyone else, often really big news he essentially breaks first and isn't remotely afraid to call people on their crap. Coulthard has his moments but can be incredibly boring. Wolff, something rubs me the wrong way about her being treated as a fully fledged driver even though the only reason she got more real driving in F1 compared to Jorda is because she was married to a part owner of the team. She's actually okay on camera but everyone treats her like she had a real shot at driving an F1 car. They did fully fledged segments on Sky following her training or something where as we all accept it would be ridiculous to do the same for Jorda.
Everyone seems to suck up to her, give her more credibility and value her opinion because she is married to Toto and is British. Maybe reading into it too much but they seem to have highlighted drivers within that picture by giving them helmets and somehow Wolff gets a helmet but Karun and Prost don't.
