First of all, why is "most likely" in quotes? It's really misleading given that the article never says anything besides the fact that Ray Allen was the "most likely" of the Big Four to be traded. And that clearly didn't happen and that's clearly not what the title of this link is implying. I really think the title of this thread should be changed.
Second, it's that silly time of year again. I'm sure Miami would love him, but unless Ray is an MLE player now, I don't see how they get him.
Overall, I think there's a good chance both are back next year. The worst possible thing Danny could do this summer is follow Joe Dumars's lead and ink a bunch of second tier players to big long term deals. Thus, if Danny doesn't find anyone he really feels is worthy of being a top 2-3 player on a future contender, it'd be a good idea to bring Ray and KG back.
By bringing them both back, he keeps the C's reputation as a good club afloat. More importantly, he retains their value, as they could once again be traded next season to either a contender looking to upgrade or as expiring deals in either a larger deal or to a team looking to dump salary.
