Since it's somehow everytime bash-button time, i'll engage in defend-button time.
Button is a WDC. Barrichello in the same machine not. Fact.
Button is a WDC. All car? Sure it did help. So, if Button was lucky for his ride, so was vettel, 4 times in a row.
Schumacher is WDC. Barrichello in the same machine not. Fact. etc etc etc.
Button has shown his quality. No, he's not the 'devil on the track' like Alonso and Hamilton seem to be. Still, what has Alonso done the past years? Still, what has Hamilton done the past years? Hamilton is 1-time Champ aswell. So is Button.
Rosberg isn't. Button showed great performances in the past years, not to be taken lightly. Canada ring a bell? And that wasn't just one occasion. Qualify 3rd on Silverstone and finished 4th. Button is beating Magnussen soundly throughout the year untill now. Magnussen shined 1 short moment in the first race and POOF!!! it's all gone.
I think button can do better than what we've seen this year, but where is the push? Atleast sergio got serious with him in some track battles. It's like kevin doesn't even exist anymore. All button needs is a good push.
OK, end of button defense.
I think Button will have another 2015 run, paired with Alonso. Honda appreciates Button, and the combination works. Alonso is the lion in the team to battle to the teeth. Button will be right there with him and guarantee the WCC.
Magnussen out. He only has this 2014 seat becuase Mclaren screwed up somewhere and somehow could not not place him.
I'm sure 2015 will be different story. So it's off for K-Mag. He's just not made of the right material.
Hamilton - Rosberg for 2015 at Mercedes. 2016 I see a Hamilton at Ferrari replacing Kimi, paired with Bianchi.
Vettel to Mercedes in 2016. Kimi stops after 2015, Button after 2017, Alonso after 2018. I think Rosberg might
exit F1 and go for Le Mans or something after 2017, too, especially if the doesnt become champion this year.
Daniel Ricciardo, Sebastien Vettel, Lewis Hamilton, Valterri Bottas and Romain Grosjean are the only names that i'd say are bound to be thoroughly present in F1 the coming years. Hulkenberg might be in there but i see him leaving for another class, too.
