If Massa is ahead of a faster Alonso, Massa is to move over. If there's only one new wing, Alonso gets it.
Compare it to:
If Button is ahead of a faster Hamilton, Button will fight like a Dog to keep position. If there's only one wing, they won't bring it. It's two new wings or none. Same with RBRs.
It's like comparing a driver who's has his entire team (including teammate) bending over for him mostly...Vs...a driver who has half the team working for him (while his teammate is out to beat him and using the other half of the team to beat him as well)
So, based on that, I can't answer.
Hamilton needs a couple of wins out of three races, to be honest. Either that, or 3 podiums and a DNF from Alonso.
He might beat Button yet, while there's 26 points between them a DNF for Button and podium would put the gap at around 10 points or less. Even if Button doesn't have a DNF he could still lose out to Hamilton if they both drive like they did this weekend.
