12 team keeper help

I am in a 12 team keeper league, going into my second year. Standard scoring, and I just found out that I am the first pick in upcoming draft. 2 keepers, I’m keeping Dalvin Cook. Who do I choose between joe mixon, Doug Baldwin or Allen Robinson? Thanks in advance

Any kind of round penalty for keepers?

No penalty’s

I’m keeping Mixon.

That’s how I felt. But concerned that there are so many potential values at running back with all the rookies. I won’t be drafting a running back for awhile starting with 3
