Help me with my QBs please!

4 pt TD league. Semifinal matchup

I’ve got Mariota and Cousins rostered. Both have struggled recently. So possible matchups for next two weeks:

Cousins vs Arizona, vs Denver
Mariota vs San Francisco, vs LA Rams
Garoppolo vs Tennessee, vs Jacksonville
Foles vs New York Giants, vs Oakland.

Is Foles the play here? Rest of my team is solid, and looking for the safe play. Thanks Footclan!
