Miami Dolphins at New England Patriots: 2025 Week 18 NFL Pick

Miami Dolphins (7-9) at New England Patriots (13-3)

I made a big bet on the Dolphins last week as 6-point home underdogs against the Buccaneers, but that was much more a bet against the Buccaneers, who have one win since week 8 and just two wins by more than three points all season, rather than on the Dolphins. The Dolphins won that game straight up, but they needed to win the turnover battle by three to do so, which is not consistent week-to-week. First down rate and yards per play are much more consistent and the Dolphins lost the first down rate battle (-8.23%) and yards per play battle (-0.51) to a Buccaneers team that ranks 20th and 28th in those metrics respectively. 

The Dolphins’ win last week also puts them in a bad spot, as teams tend to struggle after big home upset wins, covering at a 40.8% rate the week after winning as home underdogs of five points or more, including a 34.9% cover rate when they are underdogs of five or more again. Additionally, the Dolphins historically have struggled against good teams in the Mike McDaniel era, going 2-10 straight up and 3-9 ATS against teams that are .500 or better in week 11 or later. This season specifically, they are 6-2 straight up against teams with a losing record, but just 1-7 against teams that are .500 or better, with four double digit losses, three of which came on the road in their four road games against teams with a .500 or better record (8-8 Carolina is the one exception).

Making matters worse, the Dolphins will be without two of their best offensive playmakers, running back De’Von Achane and tight end Darren Waller, this week due to injury. Despite this, the Dolphins are only 10.5-point underdogs in New England this week, against a Patriots team that is one of the best in the league and that is getting healthier this week, with wide receiver Kayshon Boutte, left tackle Will Campbell, and defensive tackle Milton Williams all set to return. 

This line has crept up to 11 or 11.5 since I locked this in at 10.5 earlier this week, but I still like the Patriots a lot at that number. One potential concern is the Patriots pulling starters late if the Broncos are up big on the short-handed Chargers, which would eliminate the Patriots from contention for the #1 seed, but the Broncos have two double digit wins all year and play a lot of close games, so I am not really concerned about that. The Patriots are my top pick this week.

Seattle Seahawks at San Francisco 49ers: 2025 Week 18 NFL Pick

Seattle Seahawks (13-3) at San Francisco 49ers (12-4)

The 49ers have been on fire since getting quarterback Brock Purdy back from injury, winning six straight games while Purdy has played at a borderline MVP level over that stretch. This week, he will be without left tackle Trent Williams due to injury, but he will get tight end George Kittle back after he missed his sixth game of the season due to injury last week. As a result of their recent winning streak, the public seems to not understand why the Seahawks are favored by a point on the road in this game, betting on the 49ers heavily. The Seahawks are a big step up from the teams they have played on their winning streak though, as they rank 2nd in first down rate differential (+5.55%) and 1st in yards per play differential (+1.34). 

The 49ers, on the other hand, rank 7th in first down rate differential (2.35%) and 18th in yards per play differential (-0.07). Part of that is due to the injuries the 49ers have had this season and they are overall healthier than they have been, but my roster rankings still suggest the oddsmakers are right to favor the visitor in this game and, if anything, this line is a little short, with my calculated line at -2.5. There isn’t nearly enough here for the Seahawks to be worth betting, but they should be the right side for pick ‘em purposes.

Carolina Panthers at Tampa Bay Buccaneers: 2025 Week 18 NFL Pick

Carolina Panthers (8-8) at Tampa Bay Buccaneers (7-9)

I have had a lot of success betting against the Buccaneers in recent weeks. They started the season 5-1, but were never as good as their record suggested, with four of those five wins coming by three points or fewer. Since then, the Buccaneers have gone 2-8 with only one ATS cover in their last ten games, including eight straight non-covers. They still are alive for a playoff spot, but only because they play in the weakest division in the NFL. 

Unfortunately, we’re not really getting good line value going against the Buccaneers anymore, as their record now largely lines up with where they rank in first down rate differential (20th at -0.91%) and yards per play differential (28th at -0.62). The Buccaneers are also starting to get healthier. Quarterback Baker Mayfield and wide receiver Emeka Egbuka are clearly playing at less than 100%, while starting cornerback Jamel Dean joins fellow starting cornerback Zyon McCollum on the sidelines this week, but left tackle Tristan Wirfs (5 games missed), right tackle Luke Goedeke (6 games missed), running back Bucky Irving (7 games missed), and wide receivers Mike Evans (9 games missed), Chris Godwin (8 games missed), and Jalen McMillan (13 games missed) have all returned from multigame absences.

On top of that, the Buccaneers’ opponents this week, the Carolina Panthers, have been much worse in yards per play differential (26th at -0.57) and first down rate differential (26th at -1.89%) than their record would suggest. As evidence of how the public perception of the Buccaneers have shifted in just the past two weeks, the Buccaneers were 3-point road favorites in Carolina two weeks ago, which translates to about 7-point home favorites, but this week in this rematch they are still just 3-point favorites at home. That line is right where I have it calculated, so we aren’t getting any value with either side. I am taking the Panthers for pick ‘em purposes only because they are 7-0 ATS and 6-1 straight up as underdogs off of a loss this season, but this is a small sample size and could prove to not mean anything, so this is a no confidence pick.
