Tim Henman

From Frikipedia

Come on Tim. Fortunately he's wearing white so it won't stain.

The greatest English tennis player of a generation. Sadly.

Tim discovered the hard way that being ranked the fourth best player in the whole world and winning plenty of tournaments that didn't get on TV counts for naught in England, where everyones greatness is judged in one tournament annually. His dramatic and hilarious choking at Wimbledon every year, usually to some Eastern European bloke who only entered for a laugh, will sadly be his legacy.

Frikipedia salutes blinkered judgement.
