It was a great game and a great win, but the thing that bothered me was the overtimes largely boiled down to offensive possessions with no scheme to speak of--Portland was utterly dependent on Lillard, McCollum (and, at the end, Hood) hitting high-degree-of-difficulty shots (granted, Hood's last shot was a good one, but it came after a very difficult one from McCollum that missed and then a remarkable rebound and pass by McCollum). They hit enough of them, obviously, to win--but they kept almost losing because they had a ton of empty possessions where Lillard or McCollum just fired up crazy shots that missed. Usually after dribbling the ball into the floor for most of the possession and, at most, getting a screen or two before firing.
They needed more of an offensive plan. I realize everyone's tired, but that's the worst time to demand individual heroics over and over and over (as opposed to a single shot)--difficult shots become even more difficult with tired legs and arms. Denver got a number of easier baskets during the overtime and it wasn't because Portland's defense was poor.
