Auction Keeper help needed

I took over a team in a 14man, $200 Auction league with some odd scoring.
1pt per completion
2PPR
1 point bonus for 40yd completions and receptions
2 pt bonus for 40yd rushes
The person before me lost because they didn’t have any great pass catchers. My options are: Derrick Henry for $64, Mahomes $36, D Montgomery $28, Claypool $13, Gallup $5, , Ruggs $1 (everyone else is trash). Who do I keep? I lean Mahomes even though I normally don’t spend on a QB, but that seems like a good deal with a +per completion and bonus for long completions.
