Stafford or Rivers

Having issues here, do I start Rivers vs the Rams or Stafford against the Pats. Both are iffy matchups i think and both could be shootouts. I just don’t know who to rely on more. Last option i guess is waiver wire with a better matchup.
But yea help plz

Stafford. Rams defense is the thing of nightmares.

Stafford has a much better matchup. Pats are not an iffy matchup IMO. Lions should also be playing catch-up all night
