IF M. Lewis gets his way in Cincy, they will be trading down, or drafting defense, if they keep the #1 pick. The Lions and Texans don't need a QB, so Palmer should fall to the #4 slot UNLESS other teams trade for that #1 pick. I've heard Carolina may go for it, and they need a QB.
I think Palmer would be what the Bears need, BUT they will probably have to trade up to get him, and many, many, many drafted QBs with unlimited potential have failed at the NFL level, that it is just too hard to predict who will become superstars, and who will fail!!
