Play Dalvin Cook & flex Alexander Mattison, or flex Darwin Thompson?

I’m in .5PPR Yahoo leagues, seeded to win by 6 points with Mattison in. Unsure if I should play if “safe” with Mattison, or trust DCook and play Darwin Thompson (Chiefs have played their RBs well against NE in the past). Thanks guys!

DCook is playing, I don’t think Mattison is really that “safe” to be honest. Either one of those are better options than the Chiefs… There’s no guarantee Thompson will get enough opportunity with McCoy, Ware, and Mahomes.
