Chances are you've never noticed, but certain numbers are verboten on college basketball jerseys. Starting in the 1958 season, the NCAA decreed, according to its playing rules history, that "the use of the single digit numbers one and two and any digit greater than five was prohibited."
Prior to that bit of subtraction many N.C. State players wore uniforms that included the number eight: the highest combination was 88, assigned to Bob Seitz from 1955 through 1957. While Seitz played 8 ball, Virginia players sported jerseys with a single 6, 7, 8, and 9.
Players did occasionally wear 00, which appeared sparingly on players such as UNC's Eric Montross (1991-94) and Brendan Haywood (1998-2001).
Then, for the 1999-2000 season, the NCAA decided to add No.1 and No. 2 to the authorized uniform options. Zeroes also appeared in profusion.
Each year since '00, single-digit numerals in the allowable range multiplied. The first 1 through 5 straight flush appeared at N.C. State in 2001, followed by Georgia Tech in 2003 and 2005, UNC in 2009, and Clemson in 2009 and 2010. Wake Forest went the 0-4 route in 2005; Florida State followed suit (so to speak) in 2010.
This year ACC players have broken new ground, with FSU and Virginia Tech reaching unparalleled heights of digital delight.
As for the previously nullified numbers, No. 1 is so popular every ACC team has a player wearing it except BC. Two is in vogue as well, appearing on eight rosters. On Duke, Kyrie Irving wears No. 1 and Nolan Smith goes with No. 2.
