Running Back/Defense Stack Alexander Mattison FD 8700 DK 7600 Opponent DET Proj Points FD - 20.24 DK - 22.59 MIN FD 4600 DK 3200 Opponent DET Proj Points FD - 7.92 DK - 7.92 I never like writing up my favorite team and not because I am biased. It's more due to the fact they seem to play up or down to their opponents and have been very inconsistent, hence a 5-6 record. The reason this stack shows up at #1 for me this week is that it can be used in all formats as the Vikings are in a great spot here checking all the boxes. They are pretty much in a must-win situation sitting as the 7-seed and no better matchup than against the winless Lions who will also be without their best player, D'Andre Swift. With Dalvin Cook ruled out, Alexander Mattison will once again take on the lead role in the backfield and he has a track record in this situation. His last three starts with Cook out(Week 5, week 3, & week 16 2020), he has averaged over 150 yards from scrimmage and that includes heavy involvement in the pass game. I project him getting 18-20 touches for a floor with upside of 25+. He is likely a little lower owned on FanDuel where he is the 3rd most expensive option at the position(6th on DK). I like stacking the defense with Mattison in this matchup, especially with Swift and his late game fantasy explosions out of the equation. The Vikings D has actually provided a decent floor all season as they have tallied multiple sacks in every game with at least one interception in six of their last seven games. I will have exposure to this stack in all formats this week.
