D.J. Mitchell is a hockey guy.
He's a Sabres fan. His Twitter bio indicates that he hosts a fantasy hockey podcast.
At Sunday's St. Bonaventure commencement ceremony, he showed his love – and high hopes for the Sabres having the No. 1 pick in the NHL Draft – by wearing a Sabres shirt under his gown and decorating his mortarboard.
The numbers are the combination that won the draft lottery for the Sabres. He also has used those numbers as part of his Twitter page.
