LeBron James took to Instagram on Friday to ask fans whether he should switch from No. 6, which he has worn since the 2010-11 season (his first season with the Miami Heat), back to No. 23, which he wore during his first seven NBA seasons with the Cleveland Cavaliers.

Dan Devine of Yahoo’s Ball Don’t Lie blog nicely lays out James’s uniform-number history up to this point:

When he switched jersey numbers for the 2010-11 campaign, James said he was forsaking the 23 he wore through the last three years of his prep career at St. Vincent-St. Mary High School in Akron and for the first seven years of his professional career out of deference to Michael Jordan and that he’d chosen to go with 6 for several reasons — he wore No. 6 with the U.S. men’s national basketball team, he loved former six-sporter Julius Erving, and it checked off his sons’ birth dates, one of whom was born on Oct. 6, while the other was born in June, the sixth month. (He also avoided having to ask the Heat to unretire 23, which they’d somewhat oddly raised to the rafters out of respect for Jordan, despite the fact that he never played there.)

After he announced that he was coming home to Cleveland last Friday, James posted an Instagram photo of him wearing the No. 23 Cavs jersey.

ESPN’s Darren Rovell reports that James also is considering No. 32, which he wore as a high school freshman when No. 23 wasn’t available. James’s replica jersey was the NBA’s top-selling jersey in each of the past two seasons and in six of James’s 11 seasons in the league.
