What are the odds my lineup takes tmrw/last minute change

Going into monday night down by about 54 points (half ppr 4 pt passing td) and my opponent has no one left. I have Stafford, Bijaan and Pitts playing. Only change I could make at this point is picking up Parkinson and starting him over Pitts. What are the odds I can take it and should I pick up Parkinson?
