I think what Button is doing is remarkable and he should be commended for it. It is a risk, sure. But so would have staying with a Mercedes backed team that doesn't seem to like you anymore.
Button has already achieved his goal of a WDC so he is setting himself a new target of trying to beat Hamilton in the same car. And not even Alonso could do that.
If Hamilton struggles to drive a heavily fuelled car next year (which is the current armchair expert FUD doing the rounds) then it could give Button the edge...
Even if Button does struggle to match Hamilton it's not the end of the world for him. He's not out to impress anyone - he's just trying to find his own personal limits. He's still got 3 years of job security out of it and the chance to pick up the occasional race win.
