Alexander Mattison,RB, Minnesota Vikings

Dalvin Cook (ankle) was inactive for the second time in three weeks Sunday against the Detroit Lions, and Mattison delivered his second 100-yard rushing game with at least 25 carries starting in that circumstance. In those same two games, Mattison has done his best Cook impression with 13 catches (on 16 targets) and a receiving touchdown.

Cook was surely held out against the Lions with a eye on him being full strength for Week 6 against Carolina Panthers. But he was clearly less than 100 percent when he tried to play in Week 4, so there will be questions about his availability and utility if he misses practice time again this coming week.

Mattison is somehow available in about half of ESPN leagues right now, and 25 percent of Yahoo! leagues for that matter. He should be rostered in all 12-team leagues, and it doesn’t matter if you have Cook on your roster.
