Series will be difficult for the Cavaliers.
If they won only by 1 point today, then they will more than likely lose the games at Indiana and the series will go to 7 games, because Indiana probably will win at least 1 game in Cleveland
No we can't take that as a basis for Cavaliers to be more likely lose to Indiana. Why?
Here is my wild analyzation:
Yes that is alarming and we can speculate that Cleveland Cavaliers might go into difficult way in beating the Pacers since they only lead a single point game on Game 1. If Pacers can do that then they can still make that happen again.
But on the other hand, it's impossible that the whole CAVS are not doing some preparations and keys as a factor on how they will prevent that thing to happen again. Surely some reviews are being placed right now after the game so that some measures must be taked place in action.
