Robinson (5th) or Montgomery (7th) half ppr keeper

I’m drafting 9th in a 10 team 1 keeper league. Who should I keep here?

David Montgomery by a mile

This is Allen Robinson, yes? I’m still going David Montgomery as 10 team Allen possibly slips to 3 or 4th after keepers so he can still be returned to the roster at decent value. Montgomery is going top 2 rounds easily.
