Week 4 College Fantasy Football DEF News, Outlooks
SMU Mustangs Defense
SMU's defense/special teams unit could lead the position in fantasy scoring in Week 4. This season, the Mustangs' defense and special teams have been a subpar fantasy unit, scoring 11 total fantasy points this season and averaging 3.6 fantasy points per game. However, in Week 2, when SMU faced UC Davis, they scored 10 fantasy points, while they scored a combined 1 point against Florida State in Week 1 and Louisville in Week 3. SMU welcomes Missouri State to Dallas in Week 4; Missouri State gives up the 20th most points to opposing DFST units in college football.
Per PFF, SMU generated 22 pressures against UC Davis; if they can generate a similar number against Missouri State, they could finish as one of the week's highest-scoring DSTs.
Florida State Seminoles Defense
Florida State's defense has an easy matchup in Week 4 against Central Arkansas, but can we trust them? The Seminoles opened up their season with two ranked opponents: SMU and Alabama. In their matchup with SMU, the defense performed relatively well, scoring 8 fantasy points on four forced turnovers.
However, in Week 3 against the Crimson Tide, they allowed 50 points and finished the game with negative three fantasy points. On a positive note, the team plays Central Arkansas in Week 4, which gives up the most fantasy points to opposing offenses in college football. Yahoo has the Seminoles projected for 12.55 fantasy points and ranks them as the week's seventh-best defense. RotoBaller listed them as one of the best streaming options for Week 4, as they are still available in 96% of Yahoo leagues. Fantasy owners should prioritize picking them up for this week.
Pittsburgh Panthers Defense
Pittsburgh's defense can finish Week 4 as a top-10 unit. This season, the Pitt defense has been average, posting 25 total fantasy points. They allow only 11.3 points per game, ranking 15th nationally. They also allow only 60 rushing yards per game. From a fantasy perspective, they've been a relatively high-floor option, but they have not generated enough turnovers to be an elite fantasy unit.
In Week 4, Pitt welcomes Bucknell, which is averaging only 12.8 points per game and 238 yards per game. Bucknell already has one of the worst rushing attacks in college football, with their two lead backs averaging less than 3.7 yards per carry, and as a team, they have a -0.27 EPA Per Run. Fantasy owners should expect the Pitt defense to post its season-high in sacks and turnovers in Week 4, and it should be a viable start option.
Duke Blue Devils Defense
Duke's defense lacks elite upside in a Week 4 matchup with William & Mary. Over three weeks, Duke's defense ranks outside the top 25 fantasy defenses, allowing 24 total points. They have done a good job getting after the quarterback, with seven sacks on the season; however, they have only one interception and two fumble recoveries.
Although the Blue Devils allow only 12.3 points per game, they allow 292 total yards per game. William & Mary comes into this matchup averaging 26 points per game and 336.5 yards per game, although they have not played a defense of Duke's caliber. Per PFF, Duke generated 24 total pressures against Stanford in a 35-7 Week 3 blowout win. The biggest knock on the Duke defense has been its lack of turnovers. If they can generate more than two turnovers against William & Mary, they could be a top-10 unit this week.
Utah Utes Defense
Utah has eight sacks, two fumble recoveries, and two interceptions over the last two games. Iowa State went off on Bowling Green, but look at the other two matchups. The Cyclones only mustered 303 total yards against Southeast Missouri State and 255 against Iowa. Utah's defense isn't quite as good as Iowa's, but it's close.
Close enough that Utah should be rostered in far more than 2% of leagues. The Utes have a bye in Week 5, but are good options against Kansas and Colorado teams that are in the bottom half of FBS in offense.
Michigan Wolverines Defense
The Michigan defense has registered nine sacks, two interceptions, a fumble recovery, and a touchdown in three games this year. They'll give up some points, but Iowa was shut down by Iowa State.
Don't be fooled by Iowa's putting up a ton of yards (and points) on Northern Illinois and Northern Iowa. Star running back Kamari Moulton missed last week's game and was not on the original depth chart for Week 4. Since 2021, only the service academies have fewer explosive plays than Iowa. Michigan excels at stopping what Iowa likes to do.
Houston Cougars Defense
Houston has allowed more points than we would like, but at least they are starting to force some turnovers. Houston has three interceptions and two fumble recoveries over the last two games. Georgia Southern put up a bunch of yards on Charleston Southern, but has struggled against FBS opponents. Clemson held the Eagles to 266 yards of offense. Jacksonville State held them to 369.
Houston's defense hasn't allowed a ton of yards, but they have allowed more than 20 points twice in three games. They should be able to hold the Eagles under that, but using Houston long-term may not be a chance worth taking.
