We failed to cover the teaser in Week 3 by a single point. Not ideal.

Here's what we've got for Week 4:

Seattle Seahawks at Miami Dolphins

Line: Dolphins +6.5

Teaser line: Dolphins +12.5

Russell Wilson is a top-two player in the league right now and it's not really up for debate. He has the offense performing at record-breaking pace, and it's possible they stay on that course given the state of the Seahawks' defense. Seattle ranks 31st in the NFL allowing 6.6 yards per play and dead last in giving up 8.3 yards per pass. The defense also ranks 29th on third downs and in sack percentage.

To make matters worse for the Seahawks' struggling defensive unit, rookie linebacker Jordyn Brooks and star safety Jamal Adams have both been ruled out this weekend. Cornerbacks Quinton Dunbar and Neiko Thorpe are on the wrong side of questionable, while Delano Hill - Adams' backup - also didn't practice Thursday. The secondary wasn't very good to begin with and now they are absolutely depleted as they get set to face a strong group of Dolphins pass-catchers. Ryan Fitzpatrick is heating up and will have all day to pick apart this defense.

Adding to Miami's cause is the expected return of Byron Jones to an underrated secondary. Xavien Howard is looking great after recovering from knee surgery, and the Dolphins benefit from having an extra three days to prepare. The Seahawks are coming off a pair of emotional wins and this is a prime letdown spot against the Dolphins and the ever-dangerous Fitzpatrick.

Philadelphia Eagles at San Francisco 49ers

Line: 49ers -7

Teaser line: 49ers -1

These are desperate times for the Eagles, who have had a miserable go at it through three weeks. The offensive line is banged up, Greg Ward and Zach Ertz are the only healthy pass-catchers, Doug Pederson's punting to tie, but most concerning is just how bad Carson Wentz has looked. Wentz is given a lot of breaks as a result of the Eagles' constant injuries, but he's done nothing to help his cause. His decision-making has been poor, he's looked lost in the pocket, and is missing wide-open receivers with alarming frequency. Wentz has been so bad they're not even promoting him for the broadcast.

Now the Eagles have to fly across the country following an 0-2-1 start to take on a 49ers team that's dealt with even more adversity. But the way San Francisco has handled it is worlds apart.

Kyle Shanahan's team hasn't missed a beat despite a harrowing injury list, and they're finally starting to get some key contributors back, with George Kittle and Deebo Samuel among those set to return this week. Reinforcements are a long way away for the Eagles, and so is their first win, not coincidentally.
