I really don't see how the flexibility and chemistry arguments hold much weight.
First point - we have never landed a star playerin free agency using cap space. The best we did was Al Horford this year, and he's a fringe star. Greg Monroe is a fringe star and he chose Milwaukee over us. Lemarcus Aldridge chose San Antonio over us. Kevin Durant choose Golden State over us, even after we met his prerequisite (adding Horford).
My point here is that having cap space is nice - it makes you a player in free agency. It gives you the opportunity to TRY and sign a key free agent. But there are maybe 3 or 4 star free agents any given off-season, and 30 teams fighting for them (including their own teams, who can usually offer them the most money). As exciting as it is to have cap space, the actually probability of adding a big name free agent is always going to be pretty darn slim.
Secondly - as far as I'm aware, we won't axtually have cap space for a max free agent next year unless we let Amir walk (at the very least - possibly Olynyk too). Like Crowder, Amir and Olynyk are key "chemistry" part of this team (as any advanced stat will show) so the idea of adding a big name free agent without having to lose anybody in the process really isn't realistic. This season for example we added Horford, but we lost Sully and Turner. Now in order to get Horford, we had to hold off on signing Turner an Sully. While waiting to hear Horford's answer, Turner signed elsewhere. What if Horford decided to stay in Atlanta? We'd have lost Turner, we'd have been forced to re-sign Sully, and we'd have gained nothing. We just lucked out that Horford DID sign here. Even with Horford signing - we've turned out better overall, but there have been times we've really felt the loss of those Turner and/or Sully.
So the idea of adding a guy like Griffin or Hayward in free agency without losing anybody is unrealistic.
Now on that point - we can give up 'chemistry' players like Amir and Olynyk next year so we can free the cap space to HOPEFULLY sign a star (like Griffin) or a fringe-star (like Hayward). We run the risk of letting those guys walk, coming up short of free agency, and taking a step backwards.
Or we can give up one or two 'chemistry' players right now in a trade, and then we GUARANTEE that we get a star player (like Melo) or a fringe star (like Vucevic) back.
Also I would like to again re-emphasise that if we can get Melo at a somewhat reasonable cost, then there is nothing stopping us from continuing to pursue additional trades.
My first proposal would be trading Amir, Crowder, Young, 2017 Celtics 1st, 2019 Celtics 1st to New York for Carmelo Anthony.
My second proposal would be trading Zeller, Rozier and the Memphis 1st to Orlando for Vucevic.
Our roster becomes:
Vucevic
Horford
Carmelo
Bradley
Thomas
Smart
Green
Brown
Jerebko
Olynyk
Mickey
Jackson
That is enough talent to beat any team in this league in a 7 game series - including the Cavs, Spurs and even the Warriors. And we don't need to give up a single Brooklyn pick.
And if a really desirable playing comes up as a trade option later down the track (e.g. Cousins, Anthony Davis, Jimmy Butler) we sill have a plethora of trade assets in Vucevic, Smart, Brown, Bradley and both Brooklyn picks...so we aren't sacrificing any flexibility.
If no other trade options come up, then we get to use the Brooklyn picks to potentially draft a pair of top 5 picks who can then grow (along with Jaylen Brown) while getting playoff experiende on a championship caliber roster.
i don't really see the downside here.
Wow. Flexibility dont hold much weight? You don't think the Nets needed flexibility?
How about Detroit? How do you think Houston got Harden? Hell its not even clear if Carmelo makes us better instead of Crowder. Have you seen Melo play? Our issues are rebounding and defense, how the heck does Melo help that? No way is Melo worth two firsts. Id rather offer these for Hayward or Butler than Melo.
Our three best defensive players would be Avery Bradley, Al Horford, and Marcus Smart. Lets take a look at the other elite teams we are trying to beat. Does Cleveland have three players who are better then those guys defensively? Nope. How about Golden State? Nope. How about the Spurs? Nope. Clippers? No.
Hint - of all the elite teams in the league right now, none of them are studded with defensive stars. They are offensive oriented teams.
Now, on to the rebounding argument.
Part of my proposal includes adding Vucevic in a separate trade. Vucevic is a 7'0", 265 pound monster with a 7'5" wingspan. He's averaged 15 points (on 50% shooting) and 10 rebounds in 30 minutes for his career so far...and he's only 26 so he's still got upside. Rebounding problem solved.
I think that part is debatable. When locked in, Durant, Draymond and Klay are just as good defenders when compared to Bradley, Smart, and Horford.
And what is your love with Vucevic. He's a great rebounder, but does he honestly make our team that much better?
On the first point - I disagree. Draymond Green, I agree he is at least on par with Horford defensively, probably better. Klay Thompson? He's decent, but I don't believe he's as good defensively as Smart or Bradley. Durant? Every time I've seen him play his defense has been embarrassingly bad. As in 'worse the Carmelo Anthony' bad.
On the second point - yes, absolutely. Is Vucevic a big star player? Well, no. But our second starting big man is Amir Johnson, who is 6'9" and averages 6 points and 4 rebounds in 20 minutes a game.
I really like Amir when he's on the court, but the problems are:
1) He's not on the court often enough
2) He's almost a complete non-factor on offense
3) He and Horford are too small to constitute a stating front-court
4) He and Horford rebound too poorly to constitute a starting front-court
5) He and Horford have too weak an inside presence to constitute a starting front-court
Now
personally I would prefer Greg Monroe. I feel he's a more talented player, and I feel his post game and his ability to draw fouls would be more valuable to our team then Vucevic's offensive game (which is more perimeter oriented, much like Horford). But Monroe is also making about $5m more per year, which means we'd need to give up an extra rotation player (probably Jerebko) in order to match salary, and I don't really want to leave us that short handed.
Vucevic is a seven footer who has averaged 17.5 points, 9.9 rebounds and 2.5 assists over the past three seasons. He's not an all-star, but he's a very talented and massively underrated big man who is physically huge, and is still young enough to continue improving.
I recommending watching some of his highlight videos on YouTube if you aren't familar with his game - he has some really nice moves in the high post and an extremely smooth jumper.
https://www.youtube.com/watch?v=s0fYxYvH1iwhttps://www.youtube.com/watch?v=JoK9j15jzT8https://www.youtube.com/watch?v=oZNi1xSb4QUhttps://www.youtube.com/watch?v=K3Hty1KVkB0I can certainly see why Danny is intrigued given he's 26 years old, Orlando have too many bigs, and he's only making $11M a year over the next 3 years - I.e. he's actually making less money then Amir Johnson.
With Vucevic at center we'd get a major offensive boost, our rebounding issues would be as good as gone, and Horford could slip back in to his more natural PF position.
Vucevic also is a good passer (career 2.5 APG), has an outstanding midrange jumper (career 45% from 10-16 feet) and can occasionally step out and hit the open three (career 30% from three) so he fits Brad Steven's system pretty much to perfection.
My only criticisms are that he doesn't seem to play in the post enough (he is a pretty skilled post scorer, but only 22% of his shots came inside 3 feet) and like Horford he doesn't draw nearly enough fouls (16% FTR).
No matter how you look at it though, he's a very talented young big man who could make a major impact on this team. A frontcourt of Horford / Vucevic would be very tough for opponents to defend - especially smaller teams like Cleveland and Golden State.
Imagine a 7 foot Kevin Love with a less developed three point shot - that's pretty much Vucevic in a nutshell.
If you could get him cheap (like Zeller, Rozier and a pick) I can't fathom why you wouldn't jump at the chance. If you could add him AND Carmelo, then we would be up there with Golden State as one of the two or three most offensively dominant teams in the NBA.
