In the last race Vettel was held up by Hamilton and pitted too early, twice IIRC, once in an attempt to pass Hamilton that was completely the wrong move. Had it not been for that would have been interesting to see what happened. Just because Vettel's car didn't have the pace to catch 13-15 seconds he lost behind Hamilton doesn't mean he didn't have the pace to catch 2-3 seconds, didn't Vettel also have a couple awful pitstops(or was that Webber, or both), add all those up and "hammered" is too hard.
Alonso got all the luck that day and did well with it, Vettel got unlucky, partially crap pit stops, partially poor strategy in pit stop timing.
Button best in the wet, because of basically one race, for which he clearly had infinately better tyres? Don't forget he knocked Hamilton out who was, without question, destroying him on pace(and everyone), in the wettest worst conditions, yeah, he made a mistake and ended up behind button, and caught him so so so easily it was a joke, if Button hadn't pulled over, even if Hamilton hadn't passed him then I'd say there was a 99% chance he would have won that race, quite easily, without getting lucky with guys sliding off infront of him.
Schumy with a FAR FAR worse car did pretty much the best race of anyone and has always been good in the wet, its completely slipped my mind who it is but someone way down the grid is usually awesome in the rain, Hamilton is epic in the rain(if his car was remotely competitive he wouldn't be pushing so much harder than everyone else and making the mistakes pushing that hard comes with), I don't think Button is even close to being one of the top 5 best wet racers, not least because, he was behind Webber, Schumy, Vettel until the track was almost ruddy dry anyway, in the rain he was behind Schumy, as the track dried and their tyres were worse, he did better......... not sure how that makes him best in the wet in any way at all.
WIthout the safety cars(did he cause two of them) and lucky pit stop timing, yeah, when you're dead last and the choice is stay last or take a chance and pit first its NOT a difficult or brave decision, its the ONLY decision. He got VERY lucky, made a bunch of mistakes, good tyres and starting behind a safety car, otherwise he'd have been LAPS down at the end, flukey as hell, nothing more or less. some good laps, sure, but he didn't put in more great laps, he was just always on better tyres, got insanely lucky and rarely, if even at all had to make a difficult pass. AS per usual in pure driving he couldn't take Schumy or Webber to save his life, with DRS, it was embarassingly easy.
