Huh? How would you want to get Barnes with that package? I'd try and see what the asking price for a Bjelica is. Holmes, too. I also would inform what Giles would want as a FA.
For Chi. I would prefer to get Lauri for the pieces I mentioned over trading away CJ for a similar type in Love. I would take a look at Hutchinson, Gafford, Kornet. I would also take a look at free agents coming out of that team this summer like Shaq Harrison and Kris Dunn.
Basically what I'm getting at, is that ourt weaknesses are very clear: Depth, lenght, perimeter defense and closing driving lanes, wing defense, reliable long range shooting and additional playmaking.
We have also seen that Zach Collins has made little progress, much like Ant Simmons. Especially with Zach, I just don't see the instincts and bball IQ. However, Trent has taken a huge step, which will help us in the future. However, he's far from CJ when it comes to creating and scoring - even though CJ is a seive on defense. When teams start trapping, doubling and hedging Dame, CJ is the guy to go to. Trading him away opens up another can of problems. Especially if we also don't resign Melo -remember how much he has bailed us out with timely scoring.
Side note: One realistic target guy I could see replace some of what CJ does (while also having the same weakness) is Malik Monk.
Now to go to our problems:
Closing driving lanes
Reliable long range shooting
Ariza should be back next year: he is a huge help in reliable long range shooting,closing driving lanes, perimeter defense, wing defense and length. He also provides additionaL depth. Trent's continued development should help here as well. Then we have Nas Little and Jaylen Hoard who can develop into reliable wing defenders, given time (do we have that much)? I'm curious to see Wenyeen's development here as well.
I think addressing the additional weaknesses could be done by making smart moves, and targeting guys who don't open up other issues (like Harkless does - additional defense, but another 0 on the court on offense).
I would really like to see how Chandler Hutchinson's development has been - I have seen too little of the Bulls to judge. He has the tools to be a very capable defender, and his ball handling and passing on the wing could be very valuable for us. I would also love to explore getting a guy like Cody Martin - good size and defense on the wing and I loved his development as a scorer this season. Same goes for his twin brother Caleb Martin, who has been interesting. The Hornets also have Jalen McDaniels who could be a good fit for us. Then, they also have Malik Monk - who's prooooobably sort of out of favor over there. The other way around - they're said to be looking for a big man, and considering their history, they certainly have 'a type' there (Arnoldas Kulboka, Byron Mullens, Frank Kaminksy, Cody Zeller, Willy Hernangómez, Miles Plumlee, Spencer Hawes).
For Chicago, Kornet provides long range shooting, passable defense and overall just smart basketball. Should be available. I mentioned Hutchinson earlier.
Then we have the free agent market with smaller names like Shaq Harrison, Kris Dunn, Courtney Lee, Solomon Hill (although a little too much like what we've had in past years at the wing to my liking), Etwaun Moore, Jae Crowder, Deandre Bembry (good defender, decent playmaker, no shot - another Evan Turner, probably), Jakarr Sampson, Pat Connaughton, Damyean Dotson, Wesley Iwundu, David Nwaba, Frank Mason III, Orgeon product Gary Payton II, Kenrich Williams (Washington has QO but I doubt they take it - would love his fit here), and a guy like Treveon Graham would be a terrific fit. Most of these should be gettable for us, and are addressing needs we have.
Or the somewhat more popular, but older, guys like Paul Millsap, Marvin Williams, James Johnson, Aron Baynes, JaMychal Green, Garrett Temple, Dario Saric (going to demand way too much, I'm afraid), Harry Giles, Morrii brothers, Derrick Jones Jr. (Miami are among the healthies teams cap-wise this summer, so good luck there) - why not try.
Unfortunately getting someone who's a perfect fit, like Jerami Grant, will be a pipedream.
