0.5 ppr-3 keeper advice

I’m in a 3 keeper league and plan on keeping Michael Thomas and Ezekiel Elliott, but need some help on the third. My choices are Lamar jackson, miles sanders, and josh jacobs. Format is two RBs, two wrs, one qb, one te, and one flex.

Thoughts?

Thanks

take Lamar, having that advantage at QB is so much better.

Is there a keeper penalty?

If not, then I would choose Miles Sanders.
