Harrison Barnes Locked Down:
Last time out, a huge reason the Mavs battled with the Celtics was because of Harrison Barnes. He had, what may have been, the best game of his career. Barnes is a good player, don't get me wrong. But the Celtics are more than capable of shutting him down. He is not unstoppable. If the Celtics can taper down his performance of last time, they'll have no trouble getting past Dallas.
Absence of Jaylen Brown and Marcus Morris:
The C's are without both Brown and Morris tonight. There is going to be a void, no doubt. The Celtics will need someone to step up. I am assuming that Daniel Theis will fill the void of Marcus Morris. But who will fill the Jaylen Brown role? Smart, Rozier? We shall see. I would love to see Rozier have a great game.
Kyrie Kyrie Kyrie:
Kyrie Irving was absolutely unstoppable when the Celtics needed him to be last time against the Mavs. If he can go out and do that again, the Celtics will cruise to a win. There is no one on the Mavs, or in the league, that can keep this guy in front of them. The C's will rely on Kyrie tonight, no doubt.
