On paper, both Bledsoe and Knight are among the worst Point Guards in the league.
Bledsoe when healthy is one of the top 10 Point Guards in the league.
Brandon Knight is not nearly as bad as you make him out to be, he was having a nice season alongside Bledsoe. He only struggled when he was forced to be the man on a dysfunctional Hornacek team hit by injuries.
I am focusing on these prospects
#1 Simmons
#2 Ingram - does what you want from a SF, already shows the skills necessary to succeed. Outside chance due to his length that he may develop into a modern NBA PF down the road if he puts up weight/muscle.
#3-5
SF Jaylen Brown - could develop into a Jimmy Butler type player
FC Dragan Bender - long-term project
PG Kris Dunn - does a little of everything but already a 4 year Junior
#10-14
GF Denzel Valentine - 6'6 senior wing player that does everything for his team (DX#18)
FC Ivan Rabb - solid 6'11 big that rebounds, has good touch around the rim and skills in the post but not very athletic or explosive (DX#15)
FC Damion Jones - very athletic big 6'11 245lbs that runs the floor, dunks, blocks (DX#13)
FC Deyonta Davis - athletic big with motor, good agility but offensive game is not where it needs to be for a PF in the NBA (DX#12)
FC Skal Labissiere - project with upside, pick that is 100% on potential (DX#19)
SF Timothee Luwawu - athletic, 3&D wing with developing skills (DX#11)
#27-33
C Ivica Zubac - 18 yrs old high upside project, moves well (Dx#28)
FC Domatas Sabonis - solid but unspectacular (Dx#23)
PG Wade Baldwin - Athletic all-around sophomore PG (Dx#16)
SG Grayson Allen - sophomore, explosive scorer (DX#29)
PG Kay Felder - super athletic PG that does it all, but 5'9(DX#51)
SF Taurean Prince - athletic 3&D prototype (DX#22)
