A basketball player who is just starting out their career's most exciting moment happens when they find out their official NBA 2K ratings. HoopsHype spoke with Mike Stauffer to find out more about the process. Stauffer is the producer in the team that develops products for the videogame. 

His group works in conjunction with the game-play group to decide on the rating of each player who are included on NBA rosters. (Obsessive players who use the MyLeague mode in the game might also recognize Stauffer as one of the computer-generated head coaches employed by franchises to simulate the offseason.)

The team of developers had a the difficult task of assessing this year's class of rookies, prior to the outbreak of coronavirus. Many of the top prospects have experienced a different path to the NBA. The Golden State Warriors selected James Wiseman as the second. 2nd overall choice in the 2020 NBA Draft, despite his fact that he had only played in three games at the college level due to eligibility issues. LaMelo Ball was selected at No. 3 overall by the Charlotte Hornets, had a road far from traditional due to his stops in Lithuania and New Zealand before coming to the league.

"Every rating is a projection. When there's less number of Buy 2K MT Xbox samples, it's going to be trickier to nail those projections," said Stauffer. "Even coaches and general managers struggle to determine is the best player is in the selection process."
