Cozier was known for his knowledge of statistics; during a Marylebone Cricket Club tour in 1967, Brian Johnston played a practical joke on him by pretending that they were on air and asking him to recite the exact bowling figures and birthdays of the entire West Indies team, which he was naturally unable to do. Cozier was specifically requested by Kerry Packer to be one of the commentators for the World Series Cricket; Cozier believed that the general public supported the series, and during a commentary stint in the series, he sang "Blue Moon". In 1994, Cozier wrote of Brian Lara's record-breaking innings that "there was no real surprise among his countrymen, simply the feeling that his inevitable date with destiny had arrived rather more suddenly than expected." Possibly his most famous line was in 1999, after West Indies were bowled out for 51 by Australia at the Queen's Park Oval, he remarked "Where does West Indies cricket go from ’ere?". In 2007, Cozier used a lunch break in a Test match at the Riverside Ground to read a spoof email asking about cricket in Mexico; fellow commentator Jonathan Agnew had to explain the joke to him. He once remarked: "The Queen's Park Oval, exactly as its name suggests—absolutely round."
