Under certain parameters , it truly IS POSSIBLE for a league such as the SEC to over-expand.
If they add more premium NCAA FB programs, they will be looking for a corresponding increase in money, and
it's possible that the various networks are not in a position to accommodate them....
The problem can be the limit of premium TV slots to show the games.
If say, CBS already has a slate of top-notch games to fill all their time slots and get great TV ratings, they can't increase ad revenue without adding MORE time slots for games
or increasing viewership per game. The latter may not be significantly possible.
So how can you add more time slots.... air games on non-Saturdays ? on cable ?
At some point, the networks run the risk of "cannibalizing" their current offerings.
Bringing up the NFL is instructive. They grew their TV revenue by continually adding time slots....
Early game Sunday. Late game Sunday. Monday Night Football. A "special Thursday Night version of Monday Night Football".
Late season games on Saturday afternoon, Saturday evening. Sunday Night Football.
They have 5 networks going....
They have no competing Pro Football League.
People love to watch the NFL and they'll watch it at 3 a.m., if it was offered....
The SEC may be the premier college conference. Their problem is that the other networks already have contracts to show games from other conferences in their prime-time slots.
Quite true. The X factor in expansion is always the "who" is added. For instance, say the SEC added Texas, TAMU, Oklahoma and OSU. Now what if those 4 schools started to dominate the SEC, giving the conference more of a southwest feel, and on the field, HURT, current top programs like Florida, Tennessee, alabama, etc, because of new western domination? The ACC added top schools in Miami and VA Tech. and that killed the FSU dominance and made that national program take a step backwards.
It seems like the best working expansion model might be to add the schools that have strong tV numbers, that penetrate some large markets...but not to rock the boat in the on-the-field power balance. Remember the Big 8? Well, once they became the Big 12, Nebraska and Colorado took a step back...schools that carried the conference torch. Instead, the Big 12 became about the south division with Texas, TAMU, OU, etc.
