Let me ask this question. Again, understand I am not a Claussen fan....
But think any teams learned from San Diego?
They get Brees, he has a rough start, they lose faith. They make a draft day deal to get Rivers, but want to let him develop. So they keep starting Brees and look what happens. Now, they made the situation worse by not trading Brees, and instead letting him go for free in FA. Now, do I think Claussen CAN do this. No. Why? Cause if they do deal Smith, and they don't get a real Wr in there, I don't care if you are Joe Montana, you will suck.
So, I would much rather see Carolina take Green, or a much needed DL. Get the O-line back and healthy, run the damn ball, and get a top flight Wr and keep Smith. Give Claussen the chance. If he fails...guess what? You are in line to get Luck next year. Win/win IMO.
