Cavs essentially found 1st round pick production from an undrafted guy in the 2019 draft, a draft where they actually ended up with 3 1st round picks (Garland, Windler, Porter Jr).
Between all the drafted and undrafted guys in 2019 Dean ranks:
13th in 3P%
T-16th in BPM
T-18th in VORP
24th in Win Shares
He's even approaching the top 30 in total points scored, currently 38th.
Between him and Lamar, where the fuck has this player development been for the last 20 years. Credit to Koby and the coaching staff and player development staff.
