The fact that you said Arkansas being comparable to CU "is a very large stretch" says a lot about a misconception of where CU is on the college football landscape. There's too much tearing down of CU among the CSU fan base and there seems to be a view that's not based in reality.
Arkansas is an excellent football program with a lot of history. Here's a quick comparison with Colorado:
| Arkansas | Colorado |
All-Time Wins | 685 (#22) | 679 (#24) |
All-Time Win % | .58988 (#28) | .58769 (#29) |
National Titles | 1 (1964) | 1 (1990) |
Conference Titles | 13 | 26 |
Consensus All-Americans | 23 | 30 |
Heisman Trophy Winners | 0 | 1 |
Other National Player Awards | 6 | 9 |
That may be the most similar program to Colorado there is. (As a side note, we both also walked away from a conference affiliation with Texas so I've got extra respect for the Razorbacks.)
Syracuse's success is right there with both of us, too. Better on some measures. The old Eastern independents never get respect outside of their region, but that's another story.
Anyway, I do agree that there is a lot of history. Similar to the Stanford-SJSU series. But people in CO care more about the CU-CSU series than folks in the Bay Area care about that one. So that is a consideration.
In my consideration, CU has moved on from other historical connections such as we had with the Big 8 teams. There is recent precedent that says history is not what should drive these decisions. CU has to do what is best for its program in the here and now. Your post only underscored for me how much the CSU link diminishes the perception of CU.
