There does not appear to be an end in sight. It will get to the point that USC could potentially play a Division II school in an ever-expanding College Football Playoff that does not appear to be slowing down anytime soon.
In order for teams to measure themselves as successful. To do this now, programs are looking to simply keep expanding the field in order for virtually everyone to have access to the postseason tournament.
As reported by ESPN's Pete Thamel, the Big Ten is providing the idea of expanding the current system to 24 or 28 teams.
This is not inherently a good thing. At face value, it makes sense and could even seem like a positive to keep allowing more and more teams into the CFP. Just because something appears to be true at first does not make it an actual better reality.
At a certain point, the regular season and how games play out during the regular season, particularly in conference play, have to matter. By always increasing the number of teams, the meaning of the regular season continues to be watered down.
Potential help for USC
There is then also the issue of allowing teams that have not truly deserved it to have a chance of winning the national championship. That is not to say that a team once in cannot go on a hot streak and make a push in the playoffs or even win it all. Once the playoffs begin, anything can happen. That does not mean, though, that someone should have been given the chance.
By the same token, it becomes increasingly that much more difficult to distinguish teams and their resumes the further down one goes on the list. Arguments are likely to ensue if the proposed idea comes to fruition among flawed teams with potentially four losses on their resumes, including some losses that should realistically disqualify teams from consideration. The bright side of all of this is that USC will be able to have a great shot of joining the party each year, especially if future changes see the CFP expanding to about 60 or so teams.
