Grab Leinart in 2QB League? WHIR

[Doughhead]

It's a 2-QB league with a short bench. Currently have Peyton and Favre as my starters with Bulger and Culpepper as reserves (although I'll likely have to drop Culpepper to grab a defense).

I was wondering if I'm better off dropping both my reserve QBs for Leinart as a high upside backup? I could also drop Micheal Bush. Thoughts?

I personally wouldn't , Culpepper is fine to drop but at least Bulger is actually a starting QB.
