Yeah Nico's awesome for just not gaf and asking the questions everyone else wants to hear asked. Being a WDC with lifetime Paddock access probably helps in that regard. He's not worried about losing access. He's very quick on his feet and is able to subtly twist the knife or get straight to the meat of the subect when everyone else is dancing around it. He also brings a lot of good insights as a former driver that some of the other ex-drivers don't seem to want to talk about imho. Also, love Ant, Paul (too bad he's gone), & Bernie for just bringing fantastic technical and/or driving insights. Jenson's too nice to say anything remotely controversial about any of the drivers, and Martin is good if you can get past his sometimes blatant biases. Jacques is actually pretty good too, like a crazy French Canadian asshole version of Nico.
Crofty is like that big, goofy yellow lab that runs all over the yard not knowing much but not really needing to know that much (as far I'm concerned). And maybe even that's being too harsh on him imho. He knows a fair amount, but imho probably tosses silly theories and speculation into the discussion just so they get discussed & often dismissed - not necessarily because he actually believes them. He's good at being the guy that holds everything together, imho (which is much more difficult than it looks), and for me, that's all he needs to be. He's there to tie all the experts together, not to be an expert. That Harry Benjamin (?) guy seems to be being groomed for that spot, and he's pretty decent too imho.
Karun is utterly freaking useless and hopelessly annoying, other than being a decent F1 historian. For analytical or current info purposes, he's a big, long-winded bowl of shit. IMHO Ted is great in the Paddock and pitlane, bringing a lot of good info from there in a usually entertaining way.
Simon, Nat, & Naomi are good at the fluffy stuff & the three or more driver features/interviews per race weekend (2 with Lewis + 1 other Brit), so I'll allow them to stay. Karun and Crazy Danica can hit the bricks. /csb
Other than the obvious and probably understandable Brit bias in the Sky coverage, I'm good with it - although it does seem to be getting more and more dumbed down lately a la the old NBC coverage. Gonna be interesting to see what we get if Apple gets (got?) US rights tho.
