Nicknamed “The Big O” because of his size, Oliver Miller was once the heaviest man ever to play in NBA, clocking in at well over 300 lbs. This size 54 Champion jersey “Designed and Tailored Exclusively for the Dallas Mavericks” is tagged “Body length +6” so it had lots of room for the big fella. This was his only season with the Mavericks. The jersey displays moderate game use. Opening Bid $100.
