An avid reader of Football Archaeology who is researching early pro football sent the following question this morning: I have been running into almost every [team name] game in 1903 having the first half being longer than the second half. For example, the 1st half will be 25 minutes long and the second half is 20 minutes.
UNC had several late kickoffs before 1927. I found several 4:15 PM kickoffs with the last one being 1903. The last 4 PM kick was 1908.
