A huge underated problem for the Celtics is that they simply don't generate free throws. Having a PG and a C who don't get to the line hurts in this regard, Hayward still working his way back from injury also doesn't help either. Smart and Tatum don't go to the basket enough. Jaylen could be better in this area (he was in college), but he isn't usually the primary ball handler and is only one guy. So we seem to have one half the value equation (3's), but are bad at the other (ft's).
