Wallace is always a deep threat to get you those big yards and perhaps a touchdown, even against the Ravens because of his speed. I'd definitely leave him in...
In regard to DeSean and Vincent, I'd go with DeSean. It appears to me their offense is becoming stronger, whereas the Bolts are continuing to struggle. Although DeSean hasn't put up his expected numbers this year (yet), IMO Philly appears to be clicking more on offense. So long as they can reduce their penalties, I think DeSean's value will rise; Vincent's value will stay status-quo.
Everyone has their opinion, but that is mine
