Deftones should be headlining Download at this point. They're headlining Hellfest, Inmusic, Ressurection and more next year, should have been them instead of Biffy on the Download Sunday. Give them a 1:45 set and let them really flex, they've got 9 albums to draw from by now. A lot of people will always go see whoever is headlining regardless of who it is, less so for 2nd bands.
