People say Boston haven't faced a team like Dallas this postseason, but I'd argue the other way around. Boston is full of shooters, and Dallas' defense will also be tested.
PJ Washington typically gets TORCHED by Tatum whether he's on Charlotte or even Dallas this season. And if not him, who is guarding Tatum? I also think Holiday could bully the Mavs' guards and post-up or attack the basket without much resistance. I like DJJ and Dallas' frontcourt, but if Boston is moving the ball around and taking open 3s, it won't matter much either. Porzingis is also easily the best frontcourt player between both teams assuming he returns.
One more thing. In the last series, did we think Dallas had some strategy for Ant, or did Ant just not have a good series himself? If it's the latter (and I feel the same btw), then as long as JT/JB don't vomit over themselves, Dallas will get overwhelmed. I thought MIN and Ant in particular choked hard.
