I'm quite leery about Matt Flynn, his limited sampling within an offensive system vs porous defenders, his LSU 7th round pedigree, etc, but given the 2 options, no disrespect intended since you're a good poster, my strong preference would be to go with what I don't know about Flynn what I already do about Kolb.
FWIW, the same friend who's a season ticket holder near the 50yd line who told me Pace was overrated is not too impressed by what he's seen so far of Kolb.
Wisdom from a "QB Whisperer::
"No we have our FRANCHISE QB and I want to keep him rather than get 2 guys who may or may not be productive NFL players.
Palmer's situation is different and if I had my choice between Palmer and buttfumble, I'd take buttfumble"
