I think Rossi made a bad move switching to Ducati.
He may have had issues with Yamaha, but it was still a potential winner rather than a certain loser.
That was prime race time squandered that could have been used to win points leading to a possible championship.
The devil you know may be better than the devil you don't.
I also feel this way with Nicky Hayden.
His loyalty can't be discounted, but racing is a business. And like a business, a rider has to look out after number 1.
And if the bike can't fulfill the task, or management is unwilling to make the necessary changes, then it's time to think about terminating the agreement.
I hope Nicky will do well back at Honda, and I hope Rossi can find what he's looking for, but both riders are competing in a sport where stature is now a major determining factor, and all teams are now looking for humans the size of rhesus monkeys to design their bikes around. The age of "designer riders" is increasingly upon us.
