Guess that means Giro d'Italia for the mountains jersey together with Rubio and then Quintana ends up as super domestique for Mas at the Tour de France afterwards. Or the Vuelta a Espana respectively, depending on where Mas has higher ambitions. 
After Nibali was 4th and Pinot has been 5th at the Giro d'Italia recently, Quintana certainly still can show something in Italy. 
Keep in mind that after Spain, Telefonicas main business market under the Movistar brand is Latin America. Arguably after the Tour de France, in South America the Giro d'Italia still is a hugely important race due to the successes of Quintana, Rujano, Gaviria, Perez Cuapio, etc. 
To send Quintana & Rubio to the Giro d'Italia to represent your brand in Colombia makes sense!
