I don't think much needs to change, if at all. They were leading for almost 3 quarters in game 4, and Cleveland didn't take their first lead until Irving got in a zone, and had an historic playoff quarter. Cleveland shot around 70% at one point, and the Celtics were still within striking distance with around two minutes left in the game. I am very optimistic that the Celtics win game 5. I went into this series thinking the Celtics would be lucky to win one game. In no way would I have ever believed they would have lost the way they did in games 1 and 2. However, after seeing them play the last two games, I'm feeling pretty good about winning game at home.
