Every bowl season features pundits debating a playoff for big-time college football. But a more serious challenge may be emerging from the Big Ten. The Chicago Tribune  reported that Big Ten officials are talking about a plan in which the top four football teams would be removed from the Bowl Championship Series, and would instead have a playoff. The semifinal games would be played at the higher seeded institution of the two pairs. The site of the championship would be bid out. The Big Ten idea emerges amid concern among many in college football about low ratings for this year's championship game and a noted lack of excitement among fans about many bowl games.
