Yes, but to get a wider range with your triple than offered by the eagle, you've got to go to a 26 inner chainring which is smaller than the 30 Co-Mo spec'd. So my point is the range on the Eagle is a wide as a standard triple setup. I never claimed you can't have wider range with a triple( albeit with some shifting tradeoffs going to bigger front ring shifts)
Your own post further down in the thread shows that the range for the Eagle is not that much smaller than with a triple and a 26 inner ring.
