The most recent loss came against the Milwaukee Bucks, in which Thunder's stagnant offense was exploited as they scored just 85 points.OKC Thunder's biggest weakness has been a lack of a secondary scorer, someone who can shoulder the load of scoring with Shai Gilgeous-Alexander. They are averaging a dismal 106.9 points per game, which ranks 26th out of the 30 teams in the league.Key Player - Shai Gilgeous-AlexanderShai Gilegous-Alexander has been the lone bright spot for the OKC Thunder in the 2020-21 NBA seasonShai Gilgeous-Alexander has taken on the role of the primary ball handler for the OKC Thunder this season and it is safe to say that he has not disappointed. The youngster is averaging a solid 22.3 points, 6.4 assists and 5.3 rebounds per game on a respectable 38.4% shooting from the deep.Alexander leads Mark Daigneault's team in points and assists, and the head coach will be looking to the former LA Clippers youngster to carry the OKC Thunder's offense.OKC Thunder Predicted LineupGuard - Theo Maledon, Guard - Shai Gilgeous-Alexander, Forward - Luguentz Dort, Forward - Darius Bazley, Center - Al HorfordAlso Read: NBA Rumors: LA Lakers could be in the mix for Andre Drummond if a buyout deal with Cleveland Cavaliers is agreed uponCleveland Cavaliers PreviewSTATUS UPDATE: Cavs Guard Matthew Dellavedova was evaluated today at Cleveland Clinic Courts after alerting team medical and athletic training staff of pain he was experiencing in his lower right abdomen.DETAILS: https://t.co/x632EuWsnw pic.twitter.com/SACh9IJUui— Cleveland Cavaliers (@cavs) February 21, 2021The Cleveland Cavaliers' problems mirror those of OKC Thunder, as they are currently the second-worst offense in the league. They have averaged just 103.9 points per game, and their defense, which was one of the best early in the season, has regressed significantly.The absence of an accomplished point guard has hurt the Cavs this season. They rank 4th in turnovers and 23rd in assists per game, with their players dishing out just 23 dimes per game. This number will have to go up as the season progresses, or the Cleveland Cavaliers could be headed to the lottery yet again.Key Player - Collin SextonCollin Sexton shoulders the scoring burden for the Cleveland CavaliersCollin Sexton has shown flashes of brilliance this season, but has struggled to be the main consistent performer for his team. However, he has still managed to tally 22.8 points per game in the 2020-21 NBA campaign, on an excellent 40.9% shooting from behind the 3 point line.Sexton will be facing a nightmare matchup in the form of defensive specialist Luguentz Dort tonight,t and the mercurial guard will have to be at his best to power the Cleveland Cavaliers to a win.Cleveland Cavaliers Predicted LineupGuard - Darius Garland, Guard - Collin Sexton, Forward - Isaac Okoro, Forward - Cedi Osman, Center - Jarrett AllenThunder vs Cavaliers Match PredictionBoth teams have struggled on offense this season, which could result in a low-scoring game.
