The real threats to the Bucks in the East are probably the Sixers, Celtics, and Heat. The Bucks are 1-3 in 4 games against those teams this year.
In those 4 games....
Giannis is 29 for 82 from the floor,
0 for 19 from 3
23 for 43 from the line.
His +/- is -29 in 135 minutes.
Maybe he's pressing too much in those games, but he turns into a "normal" player or worse against those teams so far.
