In retrospect, I think it looks like Danny did the right thing.
It is really unfair and incorrect to say he did the right thing or the wrong thing, since we don't know what "things" were truly available and what the price was.
It is quite possible Danny wanted to make a big move but nothing was on the table. It is also quite possible that big moves were on the table and Danny either balked at the price or flat out refused to trade for a rental.
When the season is over we may learn more, though I doubt it. That being said, I can't think of one legitimate reason for any fan of this team (or non-fan) to be critical of the position they are in, even if they lose to Washington.
The next 10 years are going to be something else.
