Do you really expect Scott to say anything else? Are you really that clueless? Wait don't answer that. From the article you posted we read: "Scott admitted there was some disappointment over his failure to bring Texas, Texas Tech, Texas A&M, Oklahoma and Oklahoma State into the fold. Scott swung for the fences."
So if Utah and Colorado were the original plan, why the dissappointment?
More from your article: "when Utah accepted the final invitation to be handed out."
If Utah was the first choice, why were they the last invited?
Here's an article from SI that specifically talks about Hill and Whit being ok with no being Pac10's #1 choice.

So as a matter of fact you have jack crap for proof except for homerist speculation. Your own AD and head coach admitted to being fine with not being the first choice.
Here's another one:

"when Texas picked the Big 12 over the Pac-10 and the superconference plan crumbled, it has been a foregone conclusion that the Pac-10 would revert to Plan B and invite Utah as its 12th (and final) team."
