You only have to be consistent enough to win 4 out of 7 in each round of the playoffs. You can afford short term lapses in play. Over the last two playoffs, the Bucks have failed miserably in trying to find any consistency. Everything changed on them from what it was during the regular season. For openers, the playoffs are way more physical, and the officials don't usually call it too tight, allowing them to play on.
The Bucks just weren't able to adjust to that game. Can they now? We're going to have to wait and see.
