Ray Allen has always been the 3rd member of the Big 3 and he's been very professional about that. He also has had to feel the sting of being heavily discussed at a few different trade deadlines (reportedly almost traded just a few months ago - though the details of that report are being refuted by Ainge).
So maybe it should come as no surprise that Ray seems like the least likely of the Big 3 to be back next year (despite the fact that he seems like the guy that might end up playing the longest).
Future still bright, if not Green for Ray Allen - BostonHerald.com
"It’s hard to say," Allen said of whether he remains a Celtic. "The landscape always changes over the summer. Just from what I see around the NBA, there’s a lot of teams that look forward to having me. I just want to be somewhere where I’m valued, cherished and I can go out and play.
When asked if he'd be willing to take a one year deal at an average salary, he "paused and grimaced" before answering that he wanted more stability for his family and had to be "greedy" for their sakes. Can't say that I would blame him.
I would love to see Ray Allen back next year, but I also wouldn't blame the Celtics brass if they let the market dictate his value and look for younger options before bringing and offer to Ray. If those options dried up, they might still be willing to go 2 years on a deal to bring him back. But again, all this is a discussion we should be looking further into in the offseason.
