Shai Gilgeous-Alexander and his cousin Nickeil Alexander-Walker are facing off for the first time in a playoff series as the OKC Thunder leads the Minnesota Timberwolves 3-1 in the Western Conference finals. The two were close growing up and have also played for Team Canada in international competitions.After the Thunder’s Game 4 win, where Alexander-Walker broke out for the Timberwolves, Gilgeous-Alexander expressed how proud far they have come as cousins.“At this stage, going against each other for what it felt like half a game tonight, was super fun. He got the better of me sometimes, and I got the better of him. Stuff we've dreamt about for our whole lives. It’s crazy that it has come to fruition,” said the Thunder superstar and reigning MVP Gilgeous-Alexander.Alexander-Walker topped the scoring for the Timberwolves with 23 points on 9-of-15 shooting from the field. He also made five of his eight three-pointers, four rebounds, six assists, and two steals in the game, while being the primary defender for both Gilgeous-Alexander and co-star Jalen Williams.However, it was not enough as Gilgeous-Alexander dropped 40 points, nine rebounds, and 10 assists to lead the Thunder to the grindout Game 4 win in Minnesota.After seeing Alexander-Walker impress on both ends of the floor, Shai Gilgeous-Alexander praised his cousin and believed there are more such games in him in the foreseeable future.“He was really good tonight. It felt like he barely missed,” Gilgeous-Alexander said. “The kind of night he had tonight, like he is very capable of doing that every night. It's just a matter of time before he blows.”The series now shifts to OKC for Game 5 as the Thunder is now one win away from their first NBA Finals appearance since 2012.Shai Gilgeous-Alexander makes feelings known about boos in MinnesotaShai Gilgeous-Alexander received boos from the Timberwolves crowd throughout Game 4. While it did not affect how he played in the game, Gilgeous-Alexander expressed his feelings about being a villain in Minnesota.“It’s super fun. It’s pretty up there with being at home… It’s your job to go out there and play basketball and kinda shut them up,” he said.Gilgeous-Alexander shot 13-of-30 from the field, and 12-of-14 from the free throw line to steer the Thunder to a 3-1 lead, despite the constant heckling he received from Timberwolves fans.With the series moving back to OKC for Game 5, Shai Gilgeous-Alexander is expected to be celebrated, especially if the Thunder wrap up the West finals series on their home court.
