Sebastian's guy, Rocky, seems to be a calming influence and always on top of things, very good interaction.
Pretty much the same situation with Button.
Hamilton and Latham don't seem to get along so well, but that doesn't make Latham imcompetent.
I get a feeling from Hamilton and Alonso like to be in control more than they like to be told what to do, only Alonso is better at understanding a race.
I seriously don't know why Smedley is rated so high, he is friends with Massa, talks to him like a kid and this result in very funny comments at times but being funny, specially to us looking from the outside, isn't his job description (i'm not at all blaming him for Massa's performance, just don't see what makes him so special).
The teaching Massa how to drive thing is ridiculous imo, this things happen every race with several drivers, including Vettel and Hamilton "Sebastian we need you to take less speed into turn x to protect your tires".
it's harsh how everyone likes to laugh at Massa because of that,am sure he doesn't need anyone to tell him how much speed to carry thru a corner,he is an F1 driver after all,their profession is racing. the thing is Smedley has the data in front of him and obviously it would be better to relay that to your driver...i think with a better driver they would be quite good because Smedley seems to always be keeping his driver informed about where he is and where he is losing time.
