Drop the vance dance?

I Picked up davis and was wondering if i should drop vance?
also have herndon on my bench ready for week 5

Herndon won’t be back until week 6 since it’s a 4 game suspension and they are on a bye this week.

That being said I would keep McDonald over Vernon Davis, as long as he plays this week. McDonald scores 2 TD’s from Rudolph in week 2. Neither is a great option but I think McDonald has a much higher upside.
