Maybe said "Michelin advantage" in the opening races of '06 was down to Renault winning almost all (or actually all? Don't remember) of them while Ferrari were still slow, and the Bridgestone advantage at the end down to Ferrari's stronger package?
Ferrari chose an inferior tyre-manufacturer for 2005 - their problem. Jordan and Minardi picked it, too! Surely they don't deserve to be called "2nd-best team in the Bridgestone F1 '05 cup", do they? A tyre-package is just part of the car - whoever gets the best cards has the best shot at winning. This season, then, could be called "The Non-frozen engines cup", because Ferrari and McLaren engines dominated over Renault and Honda engines. How can you argue my logic, they didn't win just three races!
Alonso and Hamilton, pace-wise, can be considered a modern-age Prost-Senna rivalry. Two equally fast drivers (and for that matter, it doesn't matter that Hamilton was a rookie - his pace is what counts) that dueled furiously, with one of them moving out at the end of the season. Fisi Vs. Prost doesn't matter - Alonso beat Fisi far more soundly than Senna beat Prost. It
is almost too much to ask of everyone on the grid to outpace Hamilton - I'm no fan of his, but his pace is phenomenal. Hamilton was slower in the first few races - but unlike Vettel & co, his learning-curve only lasted four-five races as far as raw pace is concerned, though some argue that his race-craft still isn't perfected. For the record, Hamilton only beat Alonso on countback.
Alonso moved to a
weaker Renault, a car that was 5th, 6th or even 7th-fastest at the start of the season - and through developments by the team and input from him, they turned it into a race-winner that scored more points in the last third of the season than any other driver. Hamilton remained at the strong McLaren team, winning the opening race of the season - in what was, throughout the season, always at least 2nd-fastest - so if anyone was looking for a field-topping advantage, it's the one who drove the McLaren.
Which, of course, reaches my last point: You seem to grasp that F1 isn't a spec-series - but instead of realizing it's a team's sport as well as a driver's championship, you divide the sport to categories, not by acknowledging the driver's efforts, but only giving them credit for beating their own category - Michelin's Cup, McLaren-Honda championship, Not-really-frozen-engines Cup, Force India Lawnmoving Competition, name it as you wish. At the same time, in the points-system thread, you call for an unbelievably imbalanced bias towards wins. How much will you complain that "Raikkonen only won the Ferrari cup! Hamilton should get 10000 points as well for winning the McLaren Deathmatch Shootout!"?
