That must be why NK was penalized (oh wait, I forgot there is a FIA conspiracy to make Red Bull and Vettel champions). In any case, the comparison to Alonso is not entirely fair, as the Spaniard did not have to face much adversity recently, other than not having a car with the best pace on average (by adversity, I mean things like competition and pressure from the team-mate, criticism/attacks by the media or other drivers, FIA penalties, losing many points because of car failures, etc.). Replace Massa with Hamilton in the other Ferrari, give him equal status, and see what happens then.
That's partly why Seb having 4 years alongside Webber will help him make the transition if he gets a teammate who starts beating him.
Webber has shown he can match and beat Seb and in 3 of the 4 years together, Webber lead him deep into the year (09 until Spa, 2010 until Abu Dhabi and 2012 until Hungary). He knows what its like to be behind and he knows how to come back and turn it on when it gets to the crunch.
If he went to Ferrari, Alonso getting a head start on him would not be a problem as he's been there before or if a fast driver replaced Webber, he would cope fine.
Alonso's driving superbly last 2 1/2 years but hes comfy in the situation where Massa is nowhere near as good as him and no chance of beating him over a sustained period. You suddenly throw in someone who, after 6,8,10 races is still level or ahead of him, he'll start to worry and get ragged, like in 07, then you've got a foothold and a chance of competing over 20 races. If someone gets ahead of Vettel after 8,10 races, its alright, he'll keep going and grind it out late season.
