I disagree somewhat. I like Randle's intensity and hustle every night that he plays. He could easily be played with Nance. Keep Randle at PF, put Nance at the SF (would present match-up problems for other teams) and get a guy like Whiteside in FA for the five backed-up by Black. Don't trade Randle for anybody. That is one helluva front court. With Russell and Clarkson in the backcourt we have one helluva starting young team.
You make solid points. Assuming the Lakers keep the lottery pick though, I think I'd prefer to see a frontcourt of:
C - Whiteside (maybe keep Hibbert as a backup?)
PF - Randle
SF - Simmons, Ingram or Jaylen Brown
Then have Nance coming off the bench to backup both forward spots.
