Brad Stevens inserting Semi Ojeleye into the starting lineup starting in Game 5 was truly a game-changer. His main purpose out there was to guard the Bucks phenomenon, Giannis Antetokounmpo, and to slow him down. In the regular season Semi showed us that he could do just that quite effectively.
On defense, Ojeleye takes a super-wide stance and moves his feet like Kyrie Irving dribbles the ball. His feet move like dual jackhammers and he almost always stays in front of his man.
