I think the gamble might be worth it. He's young, got a good contract, the team looks promising.
Only problem is that Merc has looked promising for yrs... but if they are finally able to breakthrough, then it should be in a solid manner (ie not likely a one-hit-wonder).
Lewis should do better than Nico, if not immediately, at least once he comes to terms with the car and team dynamics.
The whole "working on next yr's car" doesn't mean much this time around cause it seems the regs are not changing much. So, if they at least are able to catch up, anything could happen next yr... from a few podiums to even a win or so. No one knows, but Merc has been such a let down i wouldn't even bother anymore to expect them to be on form.
One thing for sure Merc will be getting is more attention... or less indifference. C'mon, could they be any duller?? Their colours even camouflage with the track!
So yeah... "That's Mercedes" threads will have more than 1 page

Came out fighting indeed.
