Deciding whether to rock No. 6 or 23 in his return to the Cleveland Cavaliers, LeBron James has a winner. “23 it is!” King James tweeted Sunday. “It’s only right I go back. 2.3=6 We still family 6. #HomeTeam #StriveForGreatness.” James wore 23 through high school and his first seven years in the NBA with the Cavs before switching to No. 6 with the Miami Heat in 2010. At the time, he cited leaving behind 23 as a tribute to Michael Jordan and encouraged the rest of the league to follow suit and never wear the number again. He chose No. 6 because his first-born son’s birthday is October 6.
