QB fill-in for Peyton Manning: K. Orton or R. Fitzpatric

[undermind]

I need to be prepared to fill in for Peyton Manning for 1 week, or all season. I grabbed Matt Hasselbeck on draft day for the heck of it as a Seahawks fan, but now I'm looking for a potential year long starter. Kyle Orton and Ryan Fitzpatrick are available in my league and I'd like to grab one of them but I'm torn. Donovan McNabb is in there too, but I'm too wary to bite on McNabb.

Thoughts?

I would go with Kyle Orton....the Bills offensive line is a mess right now and they traded away arguably their best WR in Lee Evans....I think Orton has more upside.
