I'd argue Brewer is better than Sam which means he's better than a QB who hasn't taken a 100% rep in a year, another freshman who might be great, and a 9th year sophomore I think. If you can get Charlie, you get him. He'll get concussed in week 1 since Herb can't recruit or develop OL depth so the other 3 can play then... Plus while other crappy teams in the Big 12 can win with freshman QB's, Herman can't even win with a Sr Qb...
Starting a talented freshman when you can get a grad transfer is just dumb. See OU, Ohio St, Georgia, etc...
