Sit ekeler, start singletary?

Starting dalvin cook and Chubb. Flex is between ekeler and singletary.
They talked about snap percentage yesterday on the show. Ekeler was just over 30% but had 16 touches(basically every time in the field). Singletary was over 60% and had 23 touches.
Not sure if ekeler is trending down or just how the game plan was being up all game by two scores.
