I believe that the Bucks have the oldest team in the league which is usually good in the playoffs. I do feel that coach Bud's team have underachieved in the playoffs. Maybe his lack of adjustment to the playoffs?
I actually disagree with this. Heady play is important in the playoffs, but older players often get overwhelmed with the athleticism of younger, heady players. When you look at the Bucks, I think the age and athleticism on the wings (Hill, Korver, Matthews, Middleton) might suddenly struggle to get good offensive looks.
The Celtics will and should stay home on Giannis with Smart, Ojeleye, Brown, and Hayward. The other guys will not be able to consistently create for themselves, and if Giannis is not creating for them and they can't get good looks because of the game slows down, suddenly their offense will struggle.
I'm more worried about their defense. Their defense this year is really good.
