Rodriguez was third on Angliru behind another inconsistent climber.
Evans was second on Zoncolan last year and probably climbed it faster than Rodriguez did this year. On a good day he's not bad, but he has so many bad days.
Rodríguez is a pure climber, definitely. He has all the hallmarks of them - right down to the flakiness and inconsistency due to being tiny and having pretty terrible recovery. See also: Igor Antón, José Rujano, Domenico Pozzovivo.
Certainly his best terrain appears to be short, steep walls, hence his quality on climbs like Montelupone, and wins in País Vasco and Tirreno-Adriatico (and in Mende).
But he can do the big mountains too:
2011 Dauphiné - 1st to Collet d'Allevard, 1st to La Toussuire
2010 Vuelta - 3rd to Bola del Mundo, 4th to Cotobello, and 1st to Peña Cabarga (a sort of half-and-half, as it's an MTF not a short wall, but it's a small and steep MTF)
2010 Tour - 3rd to Tourmalet, 1st to Mende (more his terrain)
2009 Vuelta - 7th to Sierra Nevada despite being in the break all day and a domestique
2008 Vuelta - 3rd to Anglirú, 4th to La Rabassa & 5th to Pla de Beret, as a domestique
2008 Giro - 3rd to Pampeago, 3rd to Tirano
He's no mug in the high mountains. He's just one of the flakiest of the pure climbers, and a more consistent guy who won't be forced to expend a bunch of energy attacking because they won't lose 10 minutes in the TT like J-Rod, can afford to ride within themselves and let him burn himself out.
