Saturday's tripleheader in the NFL wraps up with a colo sal AFC East matchup between the Dolphins and the Bills at Highmark Stadium (8:15 p.m. ET, NFL Network). The Bills are currently on a four-game winning streak and are favored by seven points on Saturday night. Meanwhile, the total is set at O/U 43.5 points due to inclement weather, according to BetMGM. Even with the weather playing a significant factor in this game, both teams have star offensive players that you need to have in your DraftKings Showdown lineup.Before we get into our lineup and strategy, here are the key scoring settings for DraftKings Showdown contests: They'refull-point PPR and there arethree-point bonuses for 300 pa sing yards, 100 rushing yards, and 100 receiving yards. The Captain pick costs 1.5 times a player's original price, but he also gets his point total multiplied by 1.5.MORE DK SHOWDOWN: Captain (1.5x points, 1.5x salary): QB Josh Allen ($10,500)Allen is starting to play better Christian Fischer Men Jersey as of late, which is good news for Bills and DFS players, as he struggled for a few weeks after the Week 7 bye. The dual-threat quarterback is coming off a solid outing last week against the Jets, where he scored 20.6 DraftKings points (194 total yards and two TDs) in not-so-great weather. He'll be battling the elements again on Saturday against a Dolphins' defense, allowing the third Giovanni Fiore Women Jersey -most DraftKings points to QBs this season (22.3). In the Bills' first matchup against the Dolphins in Week 3, Allen scored 30.7 DraftKings points in a game that came down to the last moments of the fourth quarter. The star quarterback put on a show with 447 total yards and two pa sing touchdowns. Individual DFS players should not expect that type of performance on Saturday night from Allen. However, he should play well against a struggling Dolphins' defense.FLEX WR Jaylen Waddle, Dolphins ($9,000) Waddle has had a couple of rough weeks, just like the rest of the Dolphins' offense. However, things have to turn around for him, and Saturday night's game could be a prime opportunity to do so. Last week, the second-year wide receiver had 5.1 DraftKings points (two receptions for 31 yards) as the Dolphins' offense could not do anything against the Chargers. Waddle will now focus his attention on the Bills' defense, which has allowed the 10th-most DraftKings points to WRs (36.2) this season. In their first meeting in Week 3, the young wide receiver scored 18.1 DraftKings points (four receptions for 102 yards). It might be tough for Waddle to hit for 100 yards in the snow on Saturday night. But Waddle should be in line for a bounce-back game in a must-win spot for Miami.WEEK 15 DFS LINEUPS: | FLEX WR Gabe Davis, Bills ($7,400) When it comes to the Bills WRs and NFL DFS, the go-to play is Stefon Alex Goligoski Kids Jersey Diggs, who has played outstanding this season and will be in many showdown lineups on Saturday. However, Davis sometimes gets overlooked due to his inconsistency and Diggs' play. That said, Davis might be a nice contrarian play, as the Dolphins' defense allows the 12th-most DraftKings points (36) to WRs this season. The third-year wide receiver only has five double-digit performances in NFL DFS this season. But we know that Davis does not need a ton of volume to have a big game in DFS, making him a viable option on Saturday night.FLEX RB Raheem Mostert, Dolphins ($6,200) With Jeff Wilson Jr. (hip) listed as questionable for Saturday night, there's a po sibility we could see a lot of Raheem Mostert in the Dolphins' backfield. The veteran running back didn't put a lot of points in NFL DFS (5.4 DraftKings points) last week against the Chargers. However, he had 37 yards on 11 carries, which is the most time Mostert carried the ball since Week 8 against the Lions (14 carries). With the weather not looking great, it would not be a surprise to see double-digit carries for Mostert for the second-straight week, despite Buffalo's defense allowing 99.8 rushing yards per game.WEEK 15 DFS: | FLEX TE Dawson Knox, Bills ($5,400)Knox had one of his better games last week against the Jets, scoring (season-high) 14.1 DraftKings points on four receptions ( Richard Panik Men Jersey seven targets) for 41 yards. The last time the third-year tight end had double-digit DraftKings points was in Week 11 against the Browns (14). That was also Knox's best performance from a receiving angle, as he posted seven receptions (seven targets) for 70. Knox will carry that momentum into Saturday night's contest against the Dolphins. Miami's defense has not done a great job defending the tight end this season, allowing the third-most DraftKings Oliver Ekman-Larsson Men Jersey points (15.2) and seven touchdowns. If you have Knox in your lineup, you are hoping he can score a touchdown, delivering a lot of value at a $5400 salary.FLEX DEF Bills ($4,600)The Bills' defense is getting a struggling Dolphins' team at the right time.Last week against the Jets, Buffalo's defense only gave up 10 points and had four sacks for 12 DraftKings points. The Bills' defense has been consistent throughout the season, averaging 9.1 Draftkings points per game, despite not having various players due to injury. Buffalo will look to put some pre sure on Miami QB Tua Tagovailoa, who has a 45.9 completion percentage, three touchdowns, two interceptions, and has been sacked five times in the past two games.
