There's a good interview with him (in Dutch) on the team's home page: Na de 2e plaats in 2007 en de 1e in 2008 wordt Joost Posthuma dit jaar 2e in de 3Daagse De Panne.. He says he's happy to have finished second today after having placed first last year and second the year before. The competition was greater than ever before and, although Willems edged him out, he beat Manuel Quinziato this year just as he did last year. (Quinziato ended up in fourth place.) Asked whether he's a threat at the most famous of the spring classics this weekend (the Ronde van Vlaanderen), he said the favorites are in great form and he sees himself a notch below them; still, anything can happen in a major race like that.
