When starting Hall Of Fame mode, certain parents will give you large boosts in key stats. If you want a receiver that is very fast, look for a hall of fame WR father with the note 'He was the Randy Moss of his time'. You should end up with 95 or higher speed. If you want a fast quarterback, look for a Pro Bowl or Hall of Fame QB father with the note 'He was the Michael Vick of his time'. You will be insanely fast and have good throwing power. Do not chose a father with the note 'He was his era's Tom Brady.' He will be extremely slow (55 or less speed) and not be able to outrun anyone.
