Saquon replacement full PPR? Robinson, Davis, McKinnon or Montgomery?

With Saquon gone, I am looking for a replacement. In a full PPR format and my current RBs are Ekeler and Johnson. I lean towards Robinson or Montgomery (everyone in my league hates the Bears that’s why he’s still available), but McKinnon and Davis (especially with all thosw catches) could have huge upside. Any advice would be much appreciated
