If the Celtics do not end up with a top 2 pick, I think Jaylen Brown should be a potential option. After watching some PAC-12 games and more highlights of Brown, his game reminded me of a NBA player who definitely exceed all expectations. I looked up that NBA player's college stats and they are below.
Player A
MP FG FGA FG% 2P 2PA 2P% 3P 3PA 3P% FT FTA FT% TRB AST STL BLK TOV PF PTS
27.3 5.2 11.4 .458 4.4 8.4 .526 0.8 3.0 .265 4.6 7.0 .656 5.4 1.9 0.7 0.6 3.1 3.2 15.8
Player B
MP FG FGA FG% 2P 2PA 2P% 3P 3PA 3P% FT FTA FT% TRB AST STL BLK TOV PF PTS
31.3 4.9 10.7 .455 4.4 8.4 .523 0.5 2.3 .205 2.5 3.4 .726 9.9 1.9 1.4 0.7 2.3 2.5 12.7
Jaylen Brown is Player A and Kawhi Leonard is player B. The states that stuck out to me were FG%, 2P%, 3P%, and FTA. In his 5 year, Leonard is shooting 50.4 FG% and 47.1 3P%. So there is some encouraging news if the C's draft Brown. I would not mind drafting Brown if the C's land the #3 pick but the fans will have to temper their expectations. He could turn into a stud like Leonard.
