I watched Lee's game, Horningbrook's game, the USC QB's game and then Dak Prescott for the cowboys all in one day. Lee is not ready for the NFL. There is no comparison to his accuracy and Dak's or Eli Manning's. Even Sam's at USC is way above Tanmer's.
i also made another observation. It is really hard to win college football games with a pro style, immobile QB who sits in the pocket, unless you have all American offensive linemen and some very good, big, wide receivers. Otherwise he needs to throw short, quick, slant passes that tear into a zone because an offense designed to need 3 seconds in the pocket to go through read progressions and wait for plays to develop is going to get him sacked and throwing the ball away over and over again.
