The ACC action, a move to shore up its football frailties, started a chain reaction.
Michael Tranghese, then the Big East commissioner, maintained the move was pernicious and unnecessary — wasn't there enough TV money for everybody?
"I don't know where the danger is coming from," he said of the ACC's preemptive strike.
The move forced the Big East to raid Conference USA,and that led to a domino toppling that led to the extinction of WAC football.
The other big pivot came in 2009 when the Pac-10 replaced retiring commissioner Tom Hansen with Larry Scott, a Harvard-educated former tennis pro whose primary charge was to monetize an undervalued league.
Scott then set the industry standard by making a 12-year, $3-billion deal with ESPN and Fox.
Some still question what added value Colorado and Utah brought to the conference.
"It's different for each conference," Scott said.
Scott said he needed to split into divisions and host a title game to keep his league in the national narrative.
"Big events matter," he said.
He also maintained that expanding into other states was important in the formation of the Pac-12 Networks.
Scott considered another play for Texas last year, but his presidents made it clear they were quite fat, and happy, at 12.
Interestingly, the man who predicted the 16-team "super conferences" concept now sits geographically isolated from further expansion unless Texas comes back into play.
Boise State and San Diego State are not, at this time, serious Pac-12 considerations.
"I think we're incredibly well-positioned," Scott said. "We don't see anything on the horizon we feel would put pressure on us, or provide substantial benefit, to going any bigger. Things could change. …You never say never."
Scott does not think expansion is over.
The irony is the ACC, which started this convulsion, may be the power conference most vulnerable to attack if the Big 12, which has only 10 teams, feels the need to expand.
