During the season, Dražen Petrović won the Euroscar, presented by the Italian basketball magazine Superbasket to the top player in Europe. Unlike major NBA awards, the Euroscar is awarded for a player's performance during a calendar year, and also takes into account a player's performances for his national team. In Petrović's case, the award considered his performances in 1989 for Real Madrid and the Yugoslavia national team, as well as the Blazers. This was the second of what would eventually be four Euroscars for Petrović.^{[citation needed]}
