Great post. It would be a great battle between those two. I still find it odd that Yamaha would bring him back though. Rossi and Jorge would be taking points away from each other during the season, plus with the ultimatum Rossi gave, it just seems all too easy just to let him go back.
The thing that I try to keep in mind is that Yamahas original Dream Team Plan was to keep Rossi for marketing, all the way to his retirement and beyond, while nuturing the Hot Young Gun Lorenzo. Phase one out while phasing the other in. It is what they wanted all along. Now they can get it for free by requiring Rossi to bring jumbo sponsorship dollars. Rossi and Jorge stealing points from one another? Meh!!! They will still finish the season 1st and 2nd, or 2nd and 1st. They will win the Team Championship, the Constructors Championship and the individual World Championship. Its a mega WIN for Yamaha.
The only thing that Yamaha needs to be careful about is, keeping a finger on the pulse of Jorges attitude when Rossi wins some races. If Jorge remains true to his words that "It would be good for Yamaha to have two fast riders", then all is cool. But if Jorge starts becoming pissed off, they may need to take some type of action to prevent him from looking elsewhere for a ride. Not cool, but a possible reality.
In 2008 I grew weary of Rossis ego and stopped rooting for him, and started rooting for the underdog, Jorge, to take down the Master. Well it happened in 2010. I have continued to root for Jorge while he battled Casey last year and this.
Since then Rossi has had constant and large helpings of Humble pie. Non Stop. On and off the track. If Rossi goes back to Yamaha he will be served another significant slice. An epic slice...as a number 2 rider. Over the course of all this time Jorge has been gaining experience and improving his craft. He is no longer the Hot Young Kid, he is now a seasoned veteran. If Rossi goes to Yamaha for 2013 I may just end up rooting for the humbled-old-man-underdog to take down the established Spanish King.
