SF 49ers - NY Giants American football prediction

New York Giants are 1-7 this season so far and they are most likely out of the playoffs. (They play in a weak division, maybe they make a little run but I dont think that will be enough). 

However, they play against a 49ers team which is gonna start an undrafted free agent quarterback who was unknown until last week. (You couldnt even find him on wikipedia) . But he played a good game last week, and now everyone knows him. But I just dont think he is gonna play to good games i a row and Giants have just too many offensive firepowers
