It's been almost six years since Honda's desire to call up young Moto2 ace Marc Marquez to its works line-up - as replacement for the suddenly retiring Casey Stoner - helped kill off MotoGP's rookie rule, which meant a newcomer had to spend at least a season in a premier class satellite team before joining a factory squad.
It was a rule that was both curious and short-lived, one that's difficult to imagine in the current six-manufacturer phase of MotoGP. Its most historically significant contribution is, ultimately, the way it was ditched - and what that decision subsequently paved the way for.
Marquez made an instant impact as Stoner's replacement in 2013 - the kind he almost certainly couldn't have made riding a Gresini Honda or an LCR Honda. It meant he did his learning in the spotlight, at the sharp end, for better (the poles, the wins, the title) or for worse (the Dani Pedrosa crash at Aragon, the Phillip Island disqualification).
