Stepping away from all the play-off excitement for a moment...
First, my disclaimer that I'm not a salary cap expert and I don't usually pay attention to these kinds of threads. Second, to protect myself against sounding like a total homer-idiot, let me say that the following thought is merely a question, not a trade idea, proposal or even a desire of mine...
So, here's my question. Ray Allen has a big contract expiring at the end of this year - something on the order of $17 million, give or take a few? But Boston's ability to sign FAs is based on how much money under the cap we have available, right? Not the value of Ray's expiring contract? So, if our salary considerations w/o Ray's contract next year put us only a few million under the cap (or whatever that number is), then we can only sign FAs up to that number (not including the mid-level exception, etc.)?
I'm not suggesting guys like LeBron or Wade would ever want to come to Boston, but if they did want to come, there's no way we could sign one of them this summer unless they were willing to sign for pennies, right? In other words, it's not like we have Ray's $17 million (or whatever it is) to spend on big name FAs, correct?
