Mattison, DLF's RB34, has continued his momentum higher and received an extra boost of support following Dalvin Cook's holdout. In the end, Cook has little leverage to take his holdout far into 2020 but Mattison loom's large should that happen. Even without a holdout, Mattison can produce, showing his value in 2019 as a rookie by rushing for 462 yards and a touchdown on 100 attempts in 13 game appearances. The sophomore isn't a free agent until 2023 so he's a risk-on hold as production could be sparse without an upgrade in snaps due to injury or continued holdout by Cook, but should the Vikings believe he possesses similar ability, an upgrade in role could be in the cards. He's ideally suited as a Dalvin Cook handcuff for dynasty owners.
