I'm not sure that is enough. You really need a rounded bottom outline to the shield in blue to provide a hard outline. Right now the bottom of the badge disappears into the white and orange uniforms. And you want the rounded outline to take away the downward pointing arrow.
I don't think it will hurt the brand that much to tweak it in a year or two and get something reasonable. The attachment is really to the idea of a shield, so if you make a better shield it won't be a hard sell. And let's face it, we really don't have that many rabid fans buying up and getting attached to merchandise right now.
I agree that I was surprised that the middle stripe was white and not orange. I think it plays okay as-is, but haven't tooled around with it. That might be to avoid an arrow look.
I do expect a tweak at some point, though from here any tweak might be overdone (possibly an oversimplification) for the sake of change.
And for the record, I really don't see the down arrow. The top is far bolder than the bottom and dominates the image.
