While hoodies can help spread a message, billboards are a much more effective method to really get the word out.
Utah Jazz star Donovan Mitchell has campaigned hard to win votes for the 2017-18 NBA Rookie of the Year award, claiming Philadelphia 76ers star Ben Simmons should not be eligible because he was drafted in 2016. The latest push came via billboard, as Eric Woodyard of the Deseret News pointed out:
Previously, Mitchell wore "Rookie" sweatshirts to stir the debate:
A 13th pick out of Louisville, Mitchell averaged 20.5 points, 3.7 assists and 3.7 points during the regular season. He also led the Jazz (48-34) to the fourth-best record in the Western Conference and has them one win from the second round.
