MIAMI (vs. Seattle)
The Dolphins are a lesser team, but they look capable of putting up above-average numbers. Since falling flat in their opener, they've scored 28 and 31 points the last two weeks against the Bills and Jaguars. Seattle, meanwhile, is the better of these teams, but it has been giving up ...

plenty of yards and touchdowns. And the Seahawks are making the longest possible trip east for this game, and also just lost one of their most impactful defenders (safety Jamal Adams). Not that Miami is going to spring an upset, but it looks like a middle-of-the-pack option for fantasy purposes in Week 4. ... The Dolphins have settled on Myles Gaskin as their main running back. He's a much better pass catcher than their other running backs. With 4, 6 and 5 catches in his first three games, he's currently on pace for 80 catches; of the 44 running backs in NFL history who've caught at least 80 passes, all but five finished with top-11 overall numbers in PPR scoring. And Gaskin is more than just a third-down back. He ran for over 1,000 yards in all four of his seasons in college. He looked good early in the Jacksonville game, with 7 carries for 35 yards on the opening drive. Then the Jaguars made adjustments ...

... and the game changed, with Gaskin gaining only 31 yards on his final 15 attempts. But that was more on play design and execution, rather than Gaskin not being good enough. Nice player, and they had him on the field for three quarters of their plays last week -- he's their guy. This is a special game for him, with Gaskin being from the Seattle area; he played his college ball at the University of Washington. Looks like a decent enough choice for total yards, with his run-catch ability. Three weeks in, he's averaging 51 rushing and 30 receiving yards. He's not as compelling for touchdowns. The Dolphins are using Jordan Howard as their goal-line back, and Ryan Fitzpatrick is also effective calling his own number in that part of the field. So far, those guys have scored all 4 of the team's rushing touchdowns. With Howard, that's about all they're using him for now; he's not playing elsewhere in the field. In each of the first three games, he's scored on a 1-yard run but has averaged under 1 yard per carry. Matt Breida will get a few change-of-pace carries, but he's not as good as Gaskin in the passing game. ... Ryan Fitzpatrick can be streaky, and there will probably be a game in the next month or two where they're way behind and pull him at halftime, giving Tua Tagovailoa a chance. But Fitzpatrick is playing well enough right now that there's a chance he'll finish with above-average numbers in Week 4. He passed for 328 yards and 2 TDs in his last home game, and he was pretty much flawless last week, completing 90 percent of his passes. He runs more than other quarterbacks; after three weeks, he's run for 68 yards, with a touchdown and a 2-point conversion. Considering the way Seattle is playing right now, it looks awfully likely that Fitzpatrick will rank in the top 10 in passing yards this week. This probably will be a game where Seattle scores a bunch of touchdowns early, putting the Dolphins into the mode where they're passing on every down. When the Buffalo game went that way, Fitzpatrick threw for 328, with a couple of touchdowns. The Seahawks have given up plenty of passing yards. Matt Ryan passed for 450 against them in Week 1, Cam Newton went for 397 in Week 2, and Dak Prescott went for 472 on Sunday. So we'll put Fitzpatrick down for 275 passing yards and close to 2 TDs, and we're thinking that's a conservative estimate. ... DeVante Parker is Miami's No. 1 receiver. He's the guy they go to, and there's a rapport there between him and Fitzpatrick. Parker put up the 2nd-best receiving numbers in the entire league in the second half of last year (with 802 yards and 5 TDs in his final eight games) and he still looks like that same guy. That wasn't a case of a lesser player just happening to be on a hot streak. But Parker needs to get healthy. Against Jacksonville, he was playing with a hamstring injury, and it affected his ability to get downfield for big plays. Parker averaged 16.7 yards per catch last year, but he's got to be right physically. With the amount Miami should be passing in this game, we like Parker this week. ... The other wide receivers aren't as compelling. Preston Williams has the same kind of size as Parker but isn't as fast. And he's coming off a torn ACL. They've used him around the goal line some. Williams caught a short touchdown last week and a 2-point conversion the previous week. He also dropped a touchdown in the Buffalo game. But Williams so far is averaging less than 25 yards per game. Reserve Isaiah Ford has been more productive. ... Mike Gesicki might be the best tight end in the league at going up after high throws. He was a top-10 tight end in the second half of last year, and they use him in the red zone. He's caught touchdowns two weeks in a row. Only 2 targets last week, but they were both into the end zone. Gesicki caught only 1 pass last week, but he'll be busier in this game (with the team passing more). ... We're slotting Jason Sanders as a lesser kicker. If the Dolphins fall behind early in this game, it could take them out of being able to settle for field goals. He's been a modest kicker so far, averaging 6 points in the first three games. ... The Dolphins Defense looks above-average for sacks. It's a below-average pass rush team, but it was able to put pressure on Gardner Minshew. And Russell Wilson has the history of wanting to extend plays by holding the ball. Seven years in a row he's been sacked over 40 times. But Wilson doesn't turn the ball over; he's thrown only 7 and 5 interceptions the last two years.
