The Kings need to just concentrate on realistic free agent targets. They need get a good younger Small Forward.
That means they need to go hard and focused on a younger player with upside and preferably an unrestricted free agent like Mario Hezonja, Jerami Grant or Doug McDermott.
I know that was how Geoff Petrie built the early 2000s Kings, by finding undervalued guys with upside, like Doug Chritie, Bobby Jackson, Scot Pollard.
Don't waste precious time on flirting with players like Zach Lavine, Arron Gordon, Julius Randall, and Jabari Parker. The chances of signing those players are slim and most likely the Kings would just be used as leverage to get those guys better deals elsewhere.
It is essential that the Kings get a small forward either in free agency or through a trade. You can't thrive in today's NBA without a good starting small forward.
