NFL Network's Tom Pelissero reports that the Vikings have agreed to a two-year deal with RB Alexander Mattison. The deal will pay him $7 million, with a max value of $8 million and $6.35 million guaranteed. Mattison's return will get more interesting if/when the Dalvin Cook trade rumors come true. Even in that case, Mattison's presence won't preclude Minnesota from adding someone else -- either via the NFL Draft or free agency. Don't go nuts over Mattison in best ball drafts. But he's OK to mix in as a RB4 or later RB3.
