numbers have a sentimental value. for instance my number 61 came from my brother being number 19 and us being opposites. his original number was 15 b/c his birthdate and since it was taken he transitioned to 19.
73 before Rodman kinda ruined it. For the last league I played in, I wore 10 because 7 +3 and because Im a Pearl Jam fan. That and the jerseys were numbered by size with 1 being like a Medium and 10 being a XXL.
