XI + I = X
Those of you familar with Roman numerals will recognize ^^^ states 11 + 1 = 10
Makes no sense.
Or does it?
Print it out on a piece of paper then turn the paper 180 degrees.
Now it says X = I + IX or 10 = 1 + 9
Makes perfect sense. It's all a matter of perspective.
It's the same with the Celtic's right now. Solid talent but underachieving. To discover "why" a change of perspective is likely needed.
