A little help

I’m in a 12 team 1/2 ppr fantasy football keeper league. We keep two players and have a rookie draft after the NFL draft is completed. I am keeping Ja’Mar Chase as my first round pick (rd1 pk12) and Emeka Egbuka in (rd4 pk 1). We do a snake draft which means I have the first official pick in the draft because everyone’s first keeper is their first round pick. The players that are available and that I’m considering are Puka Nacua or Christian McCaffrey. Hat is the smart choice here?
