Flaw: Presumes that new traditions cannot be created, Assumes the bowls and playoffs cannot coexist
Notre Dame used to have a tradition of not going to bowl games (they
also used to have a tradition of winning but that is another story) and
yet that was changed. The polls had a tradition of coming out before
the bowls were played and yet that was changed. All of the conferences
had a tradition of a certain number of teams and yet they were expanded
to mathematically puzzling levels (e.g. Big-10 with 11 teams).
Traditions can change and new traditions can be created. Imagine the
stories of playoff games played in Texas, Ohio State (ok, maybe not so
much), Los Angeles, Florida etc.
A scheme can be devised that lets the playoffs and bowls coexist.
Playoffs and bowls do not have to be mutually exclusive. I understand
the benefits of a bowl game to a school and city in terms of
recruiting. A playoff could be created that would maintain the bowls
and still give the top eight teams a reasonable shot at winning the
title even if they are not a traditional powerhouse or have won all
their games.
