From rec league to semi-pro, every team needs a logo. It probably won’t make you play any better, but will raise team spirit (and make you look great)!
Traditionally, team logos are emblems. Better for displaying on jerseys, hats and such. Bold colors and active poses make your mascot appear tough and intimidating, even if the chosen animal isn’t.
Depending on the sport, consider including a ball, puck, bat or shuttlecock. Certain animals can even be anthropomorphized to wear helmet and pads.
