and grab a QB who is unowned. There are always good enough options in 1 QB leagues unless the league has 16 teams.

My targets for QB this year were Richardson, Murray, or Daniels.
I ended up with Murray in both. If I'd ended up with Daniels, he'd have been my only QB.

Mayfield
Geno Smith
Jared Goff

I'd go with any of those guys for a week, or more, if Murray is hurt.
I don't need them taking a bench spot. They'll be there when I need them.

Also, some people drop those second QBs after their own bye week. when that happens, I'll have even more options.

the only position that can't really be covered well throughout a season is receiver.
