I think if there was a better TV deal in Spain, Barca & Madrid would still always be at or near the top, they would continue to have appeal. But it's a step towards additional quality teams as well, which would make the league more attractive to watch for someone who doesn't like Barca or Madrid. Increased viewership, plus the potential for other clubs to increase their worldwide fanbase, would be a good thing for La Liga. Right now Atleti are managing to be competitive, but who knows for how long they can sustain it.
