I'm just wondering if Al Davis signed him to be his starter.
Brooks also had a bad habit of not always prepping for a game by studying film or even the game plan. You can get away with that in high school or college, but an NFL defense will steal your lunch money in a heartbeat if you're not ready. Part of the blame falls on Jim Haslett, who never could control him and just let him do his thing until it was too late.
You need a Parcells or Belichik to control him, otherwise he'll revert to bad habits, and you just wasted a ton of money, and games, on a quarterback who thinks his $hit don't stink, even when he's smelling up the entire stadium.
