I think this spell between Button and Hamilton has done a great deal for Button’s reputation, and also for Hamilton’s maturity.
Button has proven that he IS in the upper leagues of F1, and whilst on balance he has been outperformed by Hamilton in terms of race results, the fact that he was close in 2010 and 2012 and beat him in 2011 has been the making of him (an odd statement for someone who came to the team as WDC I know!).
It’ll be really interesting to see how Button gets on next season as the true #1 driver in what should be a car that starts off as a race winner, along with Red Bull (based on current form and the fact that very little changes in the regs next season).
For Hamilton, he’s driven his tits off this season, and been a lot more mature and likeable this season as well. The move to Mercedes seems a little foolish, but now is the first time in his career that I feel like he has the temperament and maturity to go and drag a team up the grid and mould it around him. He’s unlikely to challenge for the title next season, but fair play to him for giving it a go.
