On the morning before he sent his sacrificial lambs out to slaughter the butcher, University of Miami coach Howard Schnellenberger gazed out a picture window in his hotel suite high above downtown Miami and wondered aloud if the Nebraska Cornhuskers realized "what a bunch of alley cats they're about to run into." He said he doubted it....Looking lordly in his Oriental smoking jacket and red felt slippers, Schnellenberger bit down on a bagel and wondered, too, if the Huskers realized they were about to get hit from the heavens by a round-eyed, curly-haired freshman quarterback who talks as if he's 30, thinks as if he's 40 and may not be spacy but is definitely from another world. "I doubt it," said Schnellenberger.
