It depends on how bad that rookie QB looked and who the QB you're talking about was. If there was an Andrew Luck type prospect then you would have to take him. There isn't so I don't see where taking another QB in the first round this year would be a good idea. Plus a couple of them will probably be off the board by then. I wouldn't be opposed to somebody in the 3rd round at the earliest if the right guy was there though.
Many were calling me crazy several years ago when I figured the Panthers would take Newton. They said the same thing except that Clausen was a 2nd round pick and not a first. They said there was no way they would spend the #1 pick in the draft on a QB after drafting Clausen in the 2nd round the year before. Thank god for them they didn't go by that thinking.
