The problem with having an only 4 team playoff is that there aren't enough major bowl games as this system would yield only 3 major bowls. Currently the BSC has 4 major bowls and then the championship a week later, 5 total major bowls.

With an 8 team playoff, play 4 major bowls as scheduled around New years Day and then the 4 winners play the next week and then the championship game the following week, 6 major bowls, every year rotating the bowls.
