The Tigers is the most common nickname for College Football teams in the United States.
Felines do very well in the NCAA.
Cat nicknames like the Tigers, Cougars, Lions, and Pumas outnumber dog nicknames like Bulldogs, Terriers, Wolves, and Huskies by more than two to one.
Other common names for college football teams include Eagles, Wildcats, Panthers, Trojans, and Spiders.
We do not know of any college football team that is named cockroach, however. Wonder why that is.
