Dish Network executive Andy LeCuyer responded Wednesday to Altitude Sports’ claim that the television provider has “refused to negotiate in good faith,” revealing an open proposal to The Denver Post that would break the months-long TV impasse. Dish’s proposal, which would put Altitude Sports back on air within 24 hours, and also includes the streaming service Sling, is a standalone, a la carte offer to fans. “Altitude tells us what to charge fans, and fans get to choose whether to purchase it or not,” LeCuyer said. Altitude has said previously an a la carte option isn’t financially sustainable. “There’s not a single regional sports network in the country that will take an at-will deal like that,” Altitude spokesman Tom Philand said.
