PLamb, I logged in specifically to give you a TP for a great post. I too think this will be a watershed moment for the team, and a mistake if the opportunity is wasted.
So far I've seen only two types of responses to your post:
1) The real issue was KG's knee.
In fact, this has little to do with PLamb's post. His post is already accounting for the bum knee, and is assuming it will stay that way. So the question becomes, why wasn't something done with such a major chip in hand (Ray's contract)?
2) We may never know what trades were available.
You may not know the specifics, but we see what the market is yielding. So far, and I'm sure there will be more, Jamison and Butler have been traded for cap space. The fact is that players ARE available for cap space. McGrady is on the move b/c of his contract, and I'd wager that there are half a dozen players who are a good young fit for this team that would have been available if Danny made the right offer with Ray.
Ultimately, I think it will be viewed as a mistake if we don't trade Ray. And I think we will look back as it as such. His contract, and his character, are a big chip to let fall off the table.
