Hi, Here is the logo idea I came up with for Northern Lights. The inner portion of the shield can easily contain whichever sport you want it to pertain to (lacrosse, baseball, etc.). We could also change the text as needed, so instead of saying "ATHLETICS" below the Northern Lights text, it could say "LACROSSE", "BASEBALL", etc.
So here are the possible options for the variation designs. You could either just the change the text, which is really quick and easy (#9), or you could add some customization like this (#9) or even this (#10).
