I think it's a fair comparison, but I'd place Cassel higher because of his ability to not to turn the ball over. Also, Smith is a competent QB who does well in a good team and will match the offenses ability. Cassel also does best with a complementing team around him, but he will make a good team better, while Smith will simply match the team around him. Cassel is not an elite QB, but he is a good QB and will rarely be the reason a team loses. I am comfortable with Matt Cassel as our starting and QBOTF. Now, if we could get a great QB that will single-handily grab the offense and carry them to victory, I wouldn't be opposed to make the change. But I really like Matt Cassel.
