Chuck Muncie, a 6'3", 220-pound All-America at California, has the size, speed and hands to overcome a New Orleans offensive line ' that opens seams instead of holes. Muncie signed a seven-year. $900,000-plus contract that included a $200,000 bonus, but he has already paid back part of the money in fines for missing planes, practices and curfews. If Muncie can get along with Coach Hank Stram, who likes to upset free-thinking souls. New Orleans could accomplish its rebuilding job almost overnight. Muncie's superstar potential, though, is obvious: one coach already calls him "a Franco Harris with good hands."
