Oklahoma City enters Thursday’s Game 3 of its first-round Western Conference series against the Memphis Grizzlies with a comfortable 2-0 lead.Comfortable as in the two Thunder victories have come by 51 and 19 points.And comfortable as in Oklahoma City has easily won both games despite less-than-stellar performances from MVP candidate Shai Gilgeous-Alexander.When the series shifts to Memphis for Games 3 and 4, Gilgeous-Alexander will attempt to regain the form that easily carried the Thunder to the Western Conference’s best record.In the series opener — a 131-80 OKC victory — Gilgeous-Alexander scored a season-low 15 points on 4-of-13 shooting. In Game 2, Alexander scored 27 points, but made only 10 of 29 shots. That included just three of his 10 3-point tries.It has been frustrating for Gilgeous-Alexander, but he’s thankful the Thunder’s talent, depth and defensive prowess has made up for his struggles.”I feel like I’m getting looks that I usually make, just missing them, that’s part of basketball,” he said. “Because my team is really good, we’ve won two games by a decent margin. They’ve had my back the last two nights.”In Game 1, Aaron Wiggins had 21 points and Jalen Williams scored 20, while Chet Holmgren contributed 19 points, 10 rebounds and two blocks. In Game 2, Williams had 24 points and Holmgren added 20 points, 11 rebounds and five blocks.Oklahoma City has dominated thanks to its trademark suffocating defense. The Thunder held Memphis to 34 percent shooting in the opener and forced 24 turnovers. In Game 2, it was more of the same. The Thunder limited Memphis to 17 first-quarter points and forced the Grizzlies to miss their first 10 shots.And it was that defense, and offensive rebounding, that allowed the Thunder to withstand a strong third quarter by the Grizzlies. Oklahoma City finished with 16 offensive rebounds in Game 2.”Our defense stayed with it,” said Thunder coach Mark Daigneault. “We still stacked stops despite not a great shooting half and not a lot of easy stuff. Our perseverance in the third quarter, just to grind through that quarter and (get offensive rebounds). We just manufactured second-half offense to win.”
