I have to add, however, to a point that consortium made:
David Luiz (my Man of the Match in Brazil's two previous games) really let Brazil down in a big way. Consortium was absolutely right; Luiz played more like a forward than a defender, rushing up to try to create opportunities, and leaving giant holes behind him as a result. Brazil seemed completely incapable of marking anyone, affording Muller and company all the space they needed to get into position.
My speculation is that Scolari's plan was to come out striking hard and put Germany off-balance; however, Fred and Hulk simply lack Neymar's speed and prowress, and Brazil was completely unprepared for Germany's counterattack. Brazil simply could not, or would not, adapt to being down, and that was what I think ultimately led to their downfall.
