Not sure if this is considered "Bold" so to speak,
but I predict Tatum has his first 30+ point game ALL season sometime during this series, which would also be a new Celtics record of youngest player to score 30 or more in a playoff game, previously held for an eternal month by Jaylen
Another bold prediction I'll make is,
Horford is going to outplay Love this series with his play on both ends of the court. Usually Love has dominated the match ups, but my gut feeling tells me Horford is going to surprise us all even more this series, like he's done the last few series. Of course, having Baynes partially helps unlike in previous years where we had soft guys like Olynyk, Zeller, Amir.
