There are many possible answers to this question right now. One of the first things I look at is boredom. You probably wonder how a team could get bored, but it happens. When you are a good as the Pacers you tend not to play at a high level all the time. This does not mean you will not be able to, but turning it on and off is not something you want to try and do all the time.
Another reason the Pacers have struggled is teams are starting to figure out how to play them. It happens and just like any other team they must adapt to it. The Miami Heat has learned this and now are two-time NBA champions. Indiana must understand this is a long race and playing well at the right time is the key. Should Pacers fans be worried?
The reality of the situation is the Pacers can beat anyone in the NBA at home or on the road. Having the best record means home court which is important, but in the playoffs any team can win anywhere. Staying healthy and being consistent is key to winning in the playoffs. The Pacers should be fine just know it will not be an easy road for them it nerver is in the NBA.
