Here is my logo for your consideration. I used an athletic typeface, in combination with a ball-talk bubble. I added laces to the ball, but it is abstract enough to pass as either a rugby ball or an american football. I would also be willing to make alternate logos with different balls, if you would like to see them
I have to step out for the evening, but I will be finalizing these new submissions first thing tomorrow morning. I still have to decide where best to place the football.
