I don't think contraction of the SEC begins in 15 years. That is more the timetable of great expansion for the SEC if it ever happens. Contraction will come after several decades more of abundant wealth that inflates the ambitions of egotistical programs within the SEC.

I think changes could come within college football that would cause a possible big decrease in popularity. That is what really must happen to break ever advancing prosperity within the SEC. I don't see that in the next several decades though.

The SECTVN is bringing in more millions to SEC members in leaps & bounds yearly as we speak. How does that transform into the type atmosphere that would lose members in 15 years?

ESPN losing subscribers from their cable channels does not effect the SECTVN. Those ESPN sports channels may be losing subscribers to the SECTVN? I do not know that as fact but whatever, ESPN & Disney both make the buck on the SECTVN as well as their cable channels.

Also, different developing cutting edge media streaming realities other than TV networks do not really indicate a big problem for conference TV Networks as we now know them. They will just adapt to those with the same pay to watch scale as the old cable TV model.
