Why is it Hamilton is downplaying his title chances for this year whilst Rosberg is expecting a lot. I've got two theories, Mercedes are either trying to confuse the opposition by having one driver loving the car and the other disliking the car, so other teams don't really know if the Mercedes is good or not. The other theory, which seems more realistic, is that Hamilton's last car was very quick and anything less than that is a bad car in his eyes, whilst Rosberg's last car was average, thereabouts, and the 2013 car is better than the 2012 car. What do you guys think?
Your second theory is a perfect explanation. The drivers have different bases to compare.
Teams cannot control every interview, or what drivers say casually, so different views will be publicised. I don't think either LH or NR are trying to play games.
