It's not that Uran did nothing. He mainly had some terrible falls that took him out quite some times. The Colombian disease.
Take for instance last Paris Nice you were discussing. He fell there again, one of the first stages, and was not fit after that.
Typical for Uran really.
Besides his fall he did the following
2007 - Tour de Suisse stage win + 9th in GC (as 20 year old)
2008 - 3rd Lombardia, 2nd and 5th in Deutschland tour stages, 2nd Volta a Catalunya
2009 - 5th Tour de Romandie
2010 - 14th Tirreno, 35th Giro, 7th Tour de Suisse, 32th Vuelta, 12th Lombardia (mainly helper)
2011 - 7th Ruta del Sol, 3rd stage Paris Nice.
Especially in his first two years as a professional he showed major potential in my opinion. Finishing on the podium of a classic like Lombardy as 21 year old is massive, so were his performances in Catalunya and Germany (before he fell).
In 2009 and 2010 he was often forced to help Valverde/Rodriguez cs at Caisse d'Epargne and never got a free role.
I expect big things of Uran this year.
And I think Lanark really does him short. There are very few riders who can podium a monument and a small tour like Catalunya at age 21.
