Randle is in his first year in the league, having suffered some back luck (face injury), inconsistent minutes and different teams. With some more consistent playing time in the NBA, he may well mature into a solid backup PG, if not a starter. Certainly, not more of a risk than a rookie PG who had never played a minute in the NBA.
I am a bit worried about Ntilikina. Before anointing him as the next Tony Parker, let's remember that TP averaged almost 15 pts and 6 assts for his French team. What are Frank's stats in Stasbourg?
And I am worried about Smith as way undersized for today's NBA.
For me Monk is the lowest-risk option. I see his floor as an effective scoring third guard off the bench, a la Vinnie Johnson.
Do you think trading Melo for Rivers is a lower-risk option vs trying to sign someone like Jrue Holiday or George Hill? How good is Rivers vs these two guys?
P.S. Just looked up Smith's height, and he is actually 6-3, so not undersized at all. Really surprised, optically looks a lot smaller, must the be unusual speed for his size that has me fooled.
