I think Lopez will be dealt. I just don't see how you justify keeping him on a team that is arguably the worst in the league, because they are trying to win and cannot. At least we know the Sixers and the Lakers are tanking.
Considering that they'll have plenty of cap space going forward, and still have draft pick problems going forward, what motivation could they possibly have to move Lopez other than looking for an upgrade?
My reasoning is that they need to acquire draft picks at all costs. They need to completely overhaul the roster. There is no way they will build a respectable franchise because of 'cap space.' Everyone has cap space now. They need to get back in the next few drafts somehow.
They are probably the worst team in the NBA. Philly and LA are trying to lose on purpose. Brooklyn? Going out every night trying to win, and still losing most of the time. They have very little talent on that team.
Lopez is the only player on the roster who will probably net a 1st round pick in return. He is playing well but is also a ticking time-bomb with his injury history. He looks healthy now. He would definitely be a good fit on a few contending teams (Dallas? Indiana? ) You have to sell high in every market and I just don't see Lopez' value ever being higher than it is right now.
If you are GM of the Nets - your team is 8-21, 3rd worst in the league behind two tanks - what are you telling yourself that makes you think you can correct this in free agency? There are probably 25 teams with the ability to sign any player you could sign next year. Who wants to join
this team? Who are you signing that makes them a playoff team in the East?
If I was GM of the Nets - I am trading Lopez and Thadeus Young. I think these guys could at least get you one late 1st rounder, if not 2. Try to find a young project return who needs reps also. The salaries coming back are the main issue, but you can take them on if they are short duration.
They can't get much worse than .265 winning percentage, so I don't see any motivation to keep Lopez at all.
