I heard a sports announcer say, 'He was the greatest athlete in all of sport.' Wouldn't it be, 'In all of sports'?<br/><br/>Is 'sport', in this context, acceptable usage?<br/><br/>PS: In Br. style, does the comma fall outside the single quote as I did above?<br/><br/>Thanks. <img class='emoticon' style='Width:19px;Height:19px;' data-delaysrc='https://uat-englishforward-forums-backend.s3.us-west-2.amazonaws.com/Emoticons/5.gif' src='https://uat-englishforward-forums-backend.s3.us-west-2.amazonaws.com/Emoticons/5.gif' alt='Emotion: wink'/>
