Need a qb in 2 qb league

So I currently have brissett and Watson and I’m unsure if it’s safe to start brissett if it becomes a run heavy game, should I pick up like Matt Moore or Ryan tannahill or roll with brisseyt

It’s a 16 team ppr

Thanks

tannehill might be in a shootout with TB. But they might control it and run more. I think it has the same possibility as brisett. I think you’re only going to be chasing for an extra few points if you try to get someone else.
