I think our current blue alt is the best alternate we've ever had. With that said, it's pretty dang boring.
I know I'm in the minority, but I am 100% in favor of a complete and total rebrand of the franchise. Sure the fishermans didn't work, but part of the reason they didn't work was because we were a disaster of a team at the time.
I envision darker "dusty/foggy" greens and blues for our main colors. I also envision bright teals, oranges and navys similar to the fisherman colors. I want to see rope texture. I want to see anchors, lighthouses, fishing boats etc.
Don't get me wrong, blue & orange are fantastic. But like I said, I want to see a rebrand. Mostly because I'm curious, and partly because I think the Isles logo/look, while classic, is incredibly boring looking.
