Fantasy Football Matchup Outlooks
Below are some fantasy football outlooks written by our NFL team here at RotoBaller, bringing you their fantasy football analysis and advice on which players to consider starting in Week 18:
Jacoby Brissett, QB, Arizona Cardinals
From Week 6 to Week 15, Brissett was the QB3 overall in all fantasy football and averaged 21.2 fantasy points per game. The 33-year-old veteran has averaged 14.05 fantasy points over his last two games. Brissett seems to have found himself in a valley with his play during the fantasy football playoffs, but he will look to climb out of it in Week 18 against the Los Angeles Rams.
Tanner McKee, Philadelphia Eagles
A sixth-round pick out of Stanford in the 2023 NFL draft, McKee has appeared in three career NFL games, all with the Eagles. His last start came in Philadelphia's final game of the 2024 season against the New York Giants, and McKee completed 27 of 41 pass attempts for 269 yards and two touchdowns. However, he could struggle in Week 18 if he's mostly surrounded by other backups on offense for the Eagles.
Baker Mayfield, QB, Tampa Bay Buccaneers
The 30-year-old won't be a very inspiring QB1 option for fantasy managers still playing for something in Week 18, although he is coming off a 346-yard passing effort with two touchdowns in last week's loss to the Miami Dolphins. In the first meeting against the Panthers two weeks ago, Mayfield threw for only 145 yards with a touchdown and an interception. After four straight games without multiple passing TDs, Mayfield has two TD passes in two of his last three games.
Malik Willis, QB, Green Bay Packers
Willis was limited in practice all week after injuring his right shoulder in the Week 17 loss to the Baltimore Ravens last Saturday. He was excellent for fantasy managers who streamed him in deeper leagues before his injury, going 18-for-21 passing for 288 yards and a touchdown as a passer while adding 60 rushing yards and two more scores on the ground. Willis is trending toward sitting out in Week 18 with the Packers resting their injured players.
Josh Johnson, QB, Washington Commanders
Even though the Eagles will be resting key starters this weekend, Johnson will be hard-pressed to help fantasy managers without left tackle Laremy Tunsil (oblique) available. The 39-year-old signal-caller made his first start of the year in last week's Christmas Day loss to the Dallas Cowboys and went 15-for-23 passing for 198 yards with no touchdowns or interceptions. Even in two-QB leagues this weekend, fantasy managers should have better options to choose from than Johnson.
