Saruman decided to join the dark lord Sauron because he thought it was the best decision at the time. After the ring was destroyed, was Middle Earth supposed to honor him because of his previous years of being good?
In the same way, Ray Allen joined the Heat because he thought that was the best decision at the time. That's his choice. Cool. Now, it just so happened that real life doesn't always work like the books/movies and in real life, the proverbial and literal ring fell in the hands of the dark lord Riley/Lebron. It sucks but them's the breaks. When it's all said and done though, Saruman can't expect a hero's welcome when he goes back to the Shire. Maybe if he fought beside us even when the temptation of the ring was great, but no, he folded. That's the difference between SaRayman and Kevin Gandalf.
I think I might've taken this analogy too far.
The Analogy is perfect.
If Ray has the right to be p---ed at the Celtics for trying to trade him (even though Rondo, and to an extent, Pierce were targets of trade rumors as well), then the fans similarly have the right to hate him.
Ray was always glorified to be the consummate professional, yet he showed his true colors in different ways.
He got mad he was benched in favor of Bradley, despite us playing better that way.
He got mad he was included in trade offers, even though Rondo was as well.
He wasnt happy having reduced role, and mostly blamed it on Rondo, even though he has clearly declined.
Him leaving for our rivals who just beat us, for a worse offer than the one we were offering is just icing on the cake.
Get over it Ray, some of us will always hate you!
