Need Help: Rivers or Fitzy???

[Fins4Ever]

Hey guys goin for 8-3 playin the 1st place team so need a big win. I need to know if i should plug in Fitzpatrick tonight and bench rivers. Matchup on paper looks good vs Broncos like he might throw alot, but good pass rush and corners for Broncos. Rivers could end up throwin 2-3 ints. Also to mention, im playin Spiller in the flex and hes starting tonight with F. Jackson out. So with that id have pretty much all the offensive tds tonight most likely. Tough too... cuz obviously im a Fins fan lol. Thanks for any help!
