LONDON, England - Lewis Hamilton has played down the impact of Ross Brawn's departure, insisting it is neither a loss to Mercedes or Formula 1.In 2013, a year after 2008 World champion Hamilton was enticed to switch from McLaren, Brawn stepped down as Mercedes team boss.'BRAWN WAS A GOOD BOSS'Hamilton said he is not worried: "When I decided to go to Mercedes, I had much greater reasons than just him. To me, that he was there was a bonus, but after I arrived, I saw that the team had a lot of talented people."Hamilton's new team bosses will be Paddy Lowe and Toto Wolff, overseen by chairman Niki Lauda.He said: "He (Brawn) was a good boss, with a very good approach, which creates a great atmosphere in the team - but this is something that is expected of a leader."Brawn has resolved to take a sabbatical from F1, and says he will only decide if he will come back in 2015 in the summer.Hamilton said even a permanent exit from the sport for Brawn will not be a blow to F1: "The sport will continue when any of us go. So no, I don't see it as a loss for the sport."
