This NBA rookie class has been stacked from top to bottom. There are a ton of potential stars from the top of draft, Deandre Ayton, Marvin Bagley 3, Jaren Jackson Jr, Trae Young and Luka doncic. The best this year has been Luka Doncic, and in my opinion he is the clear rookie of the year favorite. Trae Young has been on fire as of late putting up monster scoring numbers since the all-star break. Ayton is averaging a double-double and has under-the-radar been balling all season. Bagley and Jackson look like above average to all-star big men. The biggest steal has been Mitchell Robinson. He was the 33rd pick and is averaging a high amount of blocks even though he does not play as much as he should. Allonzo trier of the Knicks, he was undrafted and is also putting up numbers not typical of an undrafted rookie.  Like said earlier the clear winner of Rookie of the Year is Luka Doncic, he has been playing at an all-star level the entire season and he will only get better.
