Ex-Sixer Mac McClung is back in the dunk contest, seeking a record third straight title
The 6-foot-2 McClung — a standout guard in the G League who has appeared in only five NBA games — is headed back to All-Star weekend, looking to become the first person to win the league’s dunk title in three consecutive years. Nate Robinson is the only three-time dunk champion, though his didn’t come in back-to-back-to-back years.
