Of course. I just think we've seen what the best Alex Smith has to offer. He can be a good, efficient QB who manages the ball well and minimizes turnovers. But if the offense needs to be creative and needs points quick, idk how I'd feel with Smith as the guy.
Then again Dilfer won a Superbowl with amazing Defense so it's possible to win that way, but Ravens defense that year was the second greatest defensive team of all time.
