What caused so many problems for Giannis is the way Horford, Baynes, Morris, Tatum and Brown sealed the paint against Giannis by stretching their arms out to the point of almost touching each other. Wherever Giannis tried to penetrate, he had to attempt to go through at minimum two guys with perfect defensive positioning that just swarmed him. In the 2nd half it was obvious Giannis had no answer for what the C's were doing to him. On a couple drives he looked as lost as Jaylen Brown used to when he went into a blocked off paint his rookie year.
