As players start to declare for the draft we will see many declare without an agent in order to test their stock and get feedback from the league. Many of these players are raw and need more time in college but some will come out regardless. This brings me to this posts title "Could/should Celtics target a boom or bust prospect".
The players who first come to mind for me as guys who where elite college recruits who really need more time to develop but may declare and stay in the draft anyways.
Trevon Duval PG Duke, he is a freshman who was 6th in the class of 2017 espn 100 recruits
Hamidou Diallo wing UK, he is a freshman who was 11th in the class of 2016 espn 100 recruits
Mitchell Robinson Center , he would have been a freshman had he attended college was 11th in the class of 2017 espn 100 recruits
Gary Trent Jr wing duke, he is a freshman who was 8th in the class of 2017 espn 100 recruits
Anternee Simons guard, he is a 5th year highschool player who is 7th in the class of 2018 espn 100 recruits
two other player I would qualify with this above group though they do not share the same high school pe
Omar Yurtseven center NC State, sophmore
Kostas Antetokounmpo wing dayton, red-shirt freshman
Out of these 7 Robinson is typically projected just outside the lottery, Duval and Simons in the 20s, and the rest range from late 1st to undrafted. All of these players have alot of developmental potential and could prove to be steals in the future. At the same time they are also players that carry a high bust potential.
Out of that list I can particularly see DA having interest in Duval who has a similar athletic profile to Rozier or Avery Bradely and Diallo who has a similar profile to a smaller Jaylen Brown. Both players would have to spend a lot of time in Maine but could have major future value to the team.
