Let's just not have a repeat of what we saw on this forum with Willis and Costa. It takes time for the effect of new hires (and new money for that matter) to reverberate down to the track.
People on F1Tech, "The W02 is on track, and the W03 far into development. We won't see any effect from Willis and Costa until 2013. I don't know why you Merc fanbois are so excited!?!?"
Those SAME people, "The car is garbage! Obviously hiring Willis and Costa has done NOTHING!!"
Same people again, "I don't know where all this speed suddenly came from!"
--I'm calling it now. The second Mercedes stumbles in the second half of 2014, we're going to see the obligatory, "Poaching Ellis and Wood has done NOTHING!"
