You cant get better trading him therefore you should do nothing.
How do you know you can't get better by trading him? do you have inside info on the trades being offered DA?
If it were true, and it may very well end up being true, that you can't get anything to improve the team then of course you keep ray.
But if an offer comes along, and it might, that makes this team better, then you have to trade ray.
I don't want to trade ray, but much like WDL, I want whats best for the team. If that ends up being ray moving on, I'll be bummed about it, but understand.
