Ok --- so I know this is the LAST thing a lot of people want to hear, but we should just plan for Dwight in 2013 if it falls through in the next few days. And here ... is how:
1. Sign Lopez back
2. Sign Hump to a 2-yr MAX deal. Look, we already lost Ilyasova, so we were going to sign Hump ANYWAY.
Come Summer of 2013:
All Dwight has to do is "explore his FA options" and scare the team he is on... that's it. Choose a team with cap-space (Dallas) and say he's thinking of going there --- UNLESS he is traded to the Nets. The Nets offer 3 1st round draft picks and Hump's expiring for a sign-and-trade Dwight. This is the LAST year you can do this as starting the 2013-14 year, teams over the Apron can NOT receive a sign-and trade player.
So the only argument people have against this are:
"If I'm the Rockets for example, why would I do this, he can't sign as a free agent with the Nets"
Answer: You do this because he's walking to Dallas and you're basically getting 3 draft picks vs. NOTHING. Hump is an expiring so no one cares. In fact you could probably use him in a Baron-Davis type of trade to get another draft pick since he's an expiring. This is literally like EVERY other sign-and-trade. You do it because the player is leaving ANYWAY. This also avoids the whole "I don't want to take on a long-term contract" since Hump will have ONE year left.
