If the Pack 10 expands to 16 teams regardless of which 16 teams this will create a mega conference which very well could cause a domino effect for both the Big 10 and the SEC.  A move by the Pack 10 will force the Big 10 to expand to compete in football.  The SEC would probably follow to keep up with money creating 3 conference (the three best) with each conference consisting of 16 teams.  The ACC would be raided but would also pretty much be forced to expand.  Basically if you come out with 4 mega conferences consisting of 16 teams in each conference then you are one step closer to a playoff system regardless of what the BCS or NCAA says.  Conference champions would be assured of at least a shot at the National Title.  Just some thoughts on what this could mean down the road.  Personally I like the idea of the mega conference and what it would bring to the college football.  Huge money and a clear road to the National Title.
