I don't think that's the right way to go.
You want to try and build a team that will have enough talent 2-3 years from now to be very good for a long time.
You keep Melo, you move KP to 5, you move Willy to bench, you are now messing with re-building and player development.
KP is not best at 5, he won't have the same mismatch with his post game. He would be used much like he was last year, where he hovers way too much on the 3 point line and tries to take players off the dribble. I like that KP has so many skills but he should be matching up with 4's. I really like the Willy/KP tandem as one can work you on the block and set great screens with rolling, while the other can pop, drive, cut and set sreens and spot up from the 3 point line. What's missing for them is a point guard that passes the ball, someone that really understands the importance of moving the ball. If we want to really take a big risk we should either draft Ntilikina or Dennis Smith and put them in action right away with KP/Willy. That is 3 developing longterm building blocks right away working together.
The other piece I'm high on is Ron Baker. He's just such a high IQ, infectious player that does all the right things a team needs. Sets the tone on both ends. Passes the ball. Physical defense fighting through screens, not asking KP/Willy to help every time down.
Melo you deal for a young wing and draft picks. You take back a big contract and use that player for bench/depth help. If there is no good Melo deal out there, you wait. Worst case Melo plays like he does towards the end of the season.
If we are able to get a second mid-1st round pick in the draft, get more wing help with Luke Kennard or Justin Jackson.
Rotation (years in league):
Willy (1)/O'Quinn (4)
KP (2)/Thomas (5)
Jackson (0)/Kuzminskas (1)
SG/Holiday (3)
Ntilikina (0)/Baker (1)
* Could replace Ntilikina with DSJ or possibly draft Monk, and then start Baker with him.
That's a pretty young roster/rotation, with players that can get better as most of them are at 0, 1, 2 years into the league and the "vets" even are only at 4/5. A big 3 investment in KP/Willy/Ntilikina or DSJ.
Then maybe trade Melo for a 2 guard and draft pick, bring Holiday back using early bird rights. Or if you draft Monk as BPA at 8, trade Melo for a starting PG, draft pick.
With the way Cavs and Warriors are built, we should be looking to stay in the lottery another year, get as much young developing talent in the draft as possible but at the same time develop the players we have like KP/Willy/Baker and whomever we draft at 8.
I really liked how the team played the last 10 games of the season in re-build mode. High energy. No drama. Move the ball. Run the system. Play physical D. Whatever happens W-L wise, happens. We have our 2018 draft pick. Just develop players the right way. In a way, I get why KP is upset. No one actually has heard what KP is really upset about. Player development is the key step for us. KP is right about this. They have to invest fully in a re-build. No more stop gaps or trying to build a winner in Melo era.
