For Lewis Hamilton's decision to leave McLaren and join Mercedes in the Formula One circus. Hamilton's not very original reason for jumping ship is that he wants a “fresh challenge” but others may think that he still has challenges enough at McLaren including being a better team player. He says money is not the issue but Mercedes will yield “image rights” worth millions to him. The issue should have been loyalty to the team that took him on when he was 13 and has nurtured his career ever since.
