I`ll state what i just said, it`s as if you think F1 is static. Renault this year is not the same management, engineering wise etc. during the Fernando years etc. The current iteration isn`t as strong financially or R*D wise that the team was years gone by.
As for BAR-Honda-Brawn-Merc.. you have to look at what is in hand today.. not yesterday. BAR was a joke under Willis etc. Honda never really cracked the nut properly.. Brawn was hanging on a very loose string and managed to make excellent use of what they had but it`s not as if BRAWN 2009 = MERC 2010. That`s a far stretch to make. Merc came in, cleaned the house a bit and with some much needed funds, broght in a lot of new people. Time will tell in the next couple of years whether my belief is correct that Merc is stronger as team then Brawn was. That isnt to say Brawn did anything wrong, I just Ross-Mercedes is a better team the Brawn was due to access to capital to invest in its staff and increase its experience and knowledge.
Time will tell you are right. Maybe next year or maybe year after Michael. I am not so sure what next year's car is gonna be but I am adamant that Merc will one of the strongest teams on the grid as long as they have Ross on board with input or something from experienced drivers like MSC.
