I think that he means that what offer he ever gets mclarren will beat it... which will probably be right... i cant see hamilton wanting to leave, he has worked with ron for like 8 years?
There good friends and close work associates now, i cant see hamilton wanting to join a rival team, which will be the only option as they are the only competetive cars... also, the money will swing him easily, and i think that when they loose alonso he will get a lot more money...
I think Senna joined Mclaren in 1988 and stayed with them for 5yrs. However, in 1992, he was so desperate to move to Williams (who at the time had the best car), he offered to drive for Williams for free.
What Im saying is that Ron Dennis is not his father or a family member. They are obviously close, but are none the less work colleagues. Sometimes, to be successful in your profession, you have to forget your emotions and be ruthless (just like Senna, just like Alonso who got on very well with Briatore, just like MS who got on very well with Briatore). Even Mansell left Lotus, when Collin Chapman was like a father to him.
In this sport, if you let emotions rule your actions, then in this day and age, you wont be the sort of guy who will be successful. Make no doubt about it, Hamilton is not Mr Nice Guy. He is ruthless when he needs to be. If you dont believe me, then check out some of the moves he was putting on his own team mate last week in Japan, during the SC periods. You will also see some ruthlessness from him in the years to come.
Senna, Alonso, MS, Prost - they have all shown unsporting behaviour, but that is what makes them what they are. IMO last week, Hamilton also showed this unsporting behaviour towards Alonso. He also showed it to his team mate in Hungary (when he shouldve let Alonso in front on him during the final qualifying run, but refused to give way, despite the agreement with the team).
Hamilton is ruthless and will jump ship if circumstances dictate.
