Blanco is absolutely a diesel. More of a Bruseghin.
Movistar, lest we forget, are based in Egüés, Navarra, are the team to which some of the great many amateur teams in the Basque-Navarrese scene feed (the main one being Lizarte of course, from which Amador, Herrada and Iriarte have all come recently), and are the team of Miguel Indurain.
The Fundación Euskadi sponsor a lot of teams down there, and occasionally riders from outside find themselves moving through the Fundación's ranks - Samu is the most notable, but also at the moment we have the impressive-looking Victor Cabedo coming through the ranks, who is from Comunidad Valenciana but has been coming to Euskal Herria to ride for several years now and whose girlfriend is Dorleta Zorrilla, who is Basque, and who races for one of the women's teams tied to the Fundación.
Others are Basques born outside the modern "Euskal Herria", of course; then it comes down to which team has them, who backs them etc. - though many still find their way back to Euskaltel in the end. Mikel Nieve, for example, rode for the Caja Rural amateur team, which was a feeder for Abarcá Sports (Caisse d'Epargne/Movistar) at the time, before moving to Orbea-Oreka in 2008, a feeder for Euskaltel. Nieve was born in Leitza, Navarra, so you could make the argument that Movistar is more his local team than Euskaltel is, in fact. Beñat Intxausti started in a junior team linked to Iberdrola (the amateur team that Alberto Contador rode for, and which was a feeder to ONCE/Liberty Seguros) then moved to Seguros Bilbao, a Fundación Euskadi backed team.
I don't think Intxausti has ever really settled at one location, and the pressure at Euskaltel was something he struggled with.
As for who will lead Movistar? It's a good question. Before the season started we said they had an awesome support squad but looked light on actual leaders; they had plenty of riders who could do a very good job but not many that could threaten to win. Over the year, however, they've lost Bruseghin to internal suspension (though he is now back and could convincingly fill the role of leader, though he's not one for the super steep stuff, and is old), Plaza had his leg near shorn in half in early March, and has only just got back on the road now, Intxausti has probably been traumatised for life, while Soler and Tondó need no exposition.
They have been linked to Rujano, though.
