We are set to discover a hidden trait in Hamilton I think. If it will work out with Mercedes that remains to be seen though.
This is some of what DC wrote a few days ago in his Autosport column.http://plus.autospor...-mercedes-move/
McLaren's a strange team in some respects. It has all the passion and history of Ferrari, but there's often a disconnect between the senior management and drivers. I spent nine seasons there and I still feel like a stranger every time I go back to Woking. If anyone should feel welcome, it's a driver who was there for nine years, so you have to wonder whether Lewis is experiencing the same thing.
He talks pretty much about what I have noticed too and kept me from being a fan of McLaren (under Ron Dennis and Martin Whitmarsh's leadership).
From what DC wrote I can understand why Hamilton wanted to leave. Where he was going wasn't his biggest concern. But Hamilton wanted a change, and apparently McLaren didn't want anything of that. I can understand both sides. Hamilton probably feels that McLaren is more often than not a top team, but not good enough for the top spot. McLaren management knows how to be successful and for that reason they don't see the need for change.
That's like a child growing up until adulthood. There comes a time a child has grown up, and want to take charge of his/her own life. That's going to happen, and the chiild will leave parents sooner or later. However if said kid will develop and be successful with his/her own ideas remains to be seen and is a process. We'll going to see how Hamilton develops.
Maybe the experiment ends up like being the beginning of the end of LH's F1 career. Even if it becomes so, LH in my understanding is already and will be a success regardless of hte outcome of his time at Mercedes. With his decision to go to Mercedes he demonstrated his leadership skills. It's simple really. A real leader needs to have the willingness to change and make uncommon/unpopular/'unsafe' decisions. That's what Hamilton did. Besides that Hamilton has a large following, therefore he is a leader in that respect too.
Whitmarsh however is a perfect manager. He doesn't want to rock the boat, etc. Perfect attitude for his kind of job.
But it leads to predictable clashes between him and Hamilton.
So to answer to OP's question: From my POV Hamilton already rose to the Mercedes challenge when he signed the contract. If it fails, I just wish that Hamilton is given another chance to prove himself. Something that is rare in F1 (JVi a bad example of that). If he succeeds (and that's what I wish LH), the naysayers will have to eat their hats. As usual.
