I am confident the Celtics will win game 5. It's in Boston and role players, supporting cast in the Mavericks will not play as well. Kyrie will not play as well also like in games 1 and 2 vs games 3 and 4 at home in Dallas because the Celtics fans clearly own real estate in Kyrie's head. Luka on offense will be Luka but he will run out of energy to play the level of defense he played in game 4 due to lack of support from Kyrie and cast offensively. If the NBA brings out the extender refs, watch for gambling lawsuits to follow.
