Great defensive game by Semi. Giannis seems to be tailor made for him, as opposed to a Middleton, since he struggles with his shot and wants to attack the basket. Semi, who likes to give a cushion to most players, has the lateral quickness to stay in front of Giannis and the strength to maintain good position. Obviously he needs to improve a lot offensively so hopefully a summer of really working on his shot, especially those corner 3's, translates to on-court results.
As an aside, I'm really surprised at how ineffective Morris has been this series defending Giannis. So much so that Brad seems to rarely put him on him, instead opting for Horford or Semi being the primary defender.
