Dub and Jknock, you nailed it. Of course it's praiseworthy that Rossi is returning from a broken leg, but it's not exactly extraordinary in this context. At least not to the level the media attention will find ways to grandirossize it.
I expect a media tone similar to the one we just saw where the entire paddock was forced to comment on Rossi's training activity, this time requiring everybody to comment on their thoughts of returning so soon and how heroic or folly it may be.
Let's play a game:
Name the injury the rider had whilst racing and people try to guess the rider. I'll start:
Injury: broken back
(That seems rather severe right? Can you imagine the implications of re-injuring it?)
If you live in a glass house don't throw rocks.
