After many years of fiddling with the rule, the national football association
once again allowed virtually unlimited substitution.
At Iowa, it was a year of bad luck. Though the team
broke 28 UI or Big Ten records and had the best passer in the conference
in hometown boy Gary Snook, Iowa ended the season with an overall 3-6
record and only one win in the Big Ten. The Hawkeyes were in the basement
again.
