A quick survey of North American Sports logos.*
I was just curious about the use of bats, balls, sticks, pucks, helmets, ect in sports logos, so I whipped this up. Apparently basketball and baseball logos need equipment in them. Basketball especially uses equipment, with the WNBA at 76% and the NBA at 70% equipment usage in their logos. It’s also almost always a ball, minus the Rockets with their stylized hoop. The baseball teams with equipment also almost always uses a ball. Minus the Pirates and Cardinals with bats only, the Rays and Padres using bases and the Phillies using a field.
