Darwin or penny?waiver question 1/2 ppr

If you can only take one,which is it??shallow bench and dont wanna drop more than 1 player,best short and long term options from these 2??

The road to Penny getting more touches is simple, Carson going down. Thus far he’s healthy but we know his history. Darwin needs more to happen, fortunately, it is with McCoy and Williams already being questionable. If Darwin starts his ceiling is higher so I go Darwin
