Ok let's look at this from the perspective of our team rather than as a fan. First off Paul Brown will not trade Palmer so he is out.
If we trade for Kolb, he will likely cost us a first and more. If he sucks we are out a first and more. If he is good then we have to pay him a crapload of money when his contract ends in 2012 or we give him a contract extension when we trade for him and he says "you paid a 1st and more for me so freakin pay me". If he sucks we are out a 1st and more and a crapload of money.
So here is the best situation for the Cards
Sign McNabb, why? Ok I will site one game when KVB broke the guy's ankle, he got taped up and still threw 4 TD's against us, I hated him for that but damn that is toughness. He may be going to the HOF, was Warner guarenteed the HOF before coming here? He has a home here and loves the valley. He is still mobile enough to deal with our crummy oline. He would be a great mentor to Skelton, since they have similar styles. He isn't a primadona and would get along with Whissy. He and Fitz have a relationship and get along very well. He will be cheaper than KOLB. He is availible. He wants a ring, and signing with the Cards gives him the best chance of getting into the playoffs due to our weak division. Once in the playoffs anything is game.
