Matchups We Love

Josh Allen (QB, BUF)

It's a shame this one isn't being played in prime time because it figures to be filled with fireworks. After a Week 1 blunder, Allen and the Bills are back on track, easily taking down the Raiders and Commanders. He only needed to air it out 32 times because they led from wire to wire.  Miami's defense has improved from last season, but at home, Allen is a top-five option.

Stefon Diggs and Gabe Davis (WR, BUF)

Diggs is sitting at a 29% target share through three games, leading the team by a mile. He's always open and knows the opponent well this week.

After Diggs, it's Gabe Davis, who continues to produce big plays and find the end zone. While those are mostly unpredictable, taking a shot on him after two successful outings in a high-scoring, high-volume passing game makes sense.

Tua Tagovailoa (QB, MIA)

Arguably the MVP through three weeks, Tagovailoa is coming off a historic performance. The Dolphins hung 70 on Denver in an embarrassing beatdown. He'll face his toughest test of the year on the road against the Bills, but with the complement of weapons he has and the play calling of Mike McDaniel, there's no reason to shy away from him.

Tyreek Hill and Jaylen Waddle (WR, MIA)

Tyreek Hill came out with a bang, burning the Broncos secondary for a 54-yard house call. He never looked back after that, even though they were pulling their starters in the second half.

The question is more about the health of Jaylen Waddle, who missed last week with a concussion. Wide receivers outside of Hill accounted for four targets without Waddle, who returns to being a must-start now that he's cleared the protocol.

Other Matchups

Raheem Mostert and De'Von Achane (RB, MIA)

While it's impossible not to be riding high if you are a Mostert manager, it's important to recognize that 142 yards and four touchdowns are an anomaly. It's also wise to evaluate the matchup.

The Buffalo run defense has been a formidable unit since last season and currently ranks sixth in run defense DVOA. Outside of a 34-yard end around by Tre Tucker in Week 2 and the monster play for 83 yards from Breece Hall in Week 1, they've given up only 179 yards in three contests.

Mostert is still in your lineup because he has that explosiveness, but he'll need a big play or a touchdown to finish in the top 20. De'Von Achane broke onto the scene with an even greater day than Mostert, totaling 233 yards and four touchdowns.

It's going to be hard not to throw him out there, but you need to keep your expectations in check. His total touches will be affected by the status of Salvon Ahmed, who opened the week with two limited practices.

UPDATE: Ahmed is listed as questionable. If he misses, it would solidify the role for Achane.

James Cook (RB, BUF)

The same scenario occurred once again for Cook. He ripped off a nice run, positioning them inside the five-yard line, only to be vultured by Latavius Murray. He still landed inside the top 20 on the week, accumulating over 100 all-purpose yards. That is about where he comes in this week, in part because of the matchup and in part because of his pass-catching, which should be on full display.

Dalton Kincaid (TE, BUF)

Neither tight end was asked to do much because of the game script and lopsided outcome. However, Kincaid played only six fewer snaps than Dawson Knox and ran one fewer route. He also has more targets (12), receptions (11), and yards (72) than Knox on the year with a higher yards per route (0.86).

The only downside has been his shorter aDot, which ranks 27th among tight ends. The Dolphins have allowed the seventh-most fantasy points to tight ends, which is the area they've been exploited most thus far, earning Kincaid a spot in the top 12.
