The final College Football Playoff polls are finished and we now can officially answer the question, “Who’s in?” We also know that Alabama will be playing Michigan State in one semifinal game, while Clemson will be pitted against Oklahoma in the other. The winners of those games will meet in the national championship game.

Not too long ago, the system college football used to determine the national championship matchup was very different. The Bowl Championship Series, or BCS, was a selection system that relied heavily on rankings, computer models and conference championships to determine which teams got a chance to play in each of the five major bowl games: Rose, Fiesta, Sugar, Orange, and the BCS National Championship. After years of fans and teams decrying the system as fundamentally unfair, the BCS was retired for a playoff system.

Having a committee select four teams worthy of competing for a chance at the national championship, after reviewing all of the data and performances collected over the season, does sound like a system that’s more fair. However, how much of a departure did it actually bring from what would have played out with the BCS?

Using the final CFB rankings, we compare the 2015 bowl matchups with what they would have been using the old rules of the BCS:

BCS NATIONAL CHAMPIONSHIP: No. 1 Clemson vs. No. 2 Alabama
According to BCS strictures, the top two teams in the country get automatic berths to the championship game.
COLLEGE FOOTBALL PLAYOFF NATIONAL CHAMPIONSHIP: Unknown

BCS ROSE BOWL: No. 3 Michigan State vs. No. 6 Stanford
The Rose Bowl always featured the Big Ten champion and the Pac-12 champion.
2015 ROSE BOWL: No. 5 Iowa vs. No. 6 Stanford
Because Michigan State is still in the running for the national championship, this year’s Rose Bowl will feature the Big Ten runner-up against the Pac-12 champion.

BCS FIESTA BOWL: No. 4 Oklahoma vs. No. 18 Houston
The Fiesta Bowl always featured the Big 12 champion. With a 12-1 record, Houston would also receive a BCS bowl bid as the AAC champion.
2015 FIESTA BOWL: No. 8 Notre Dame vs. No. 7 Ohio State

BCS ORANGE BOWL: No. 5 Iowa vs. No. 10 North Carolina
Both teams were runner-ups in their respective conferences. However, they would both obtain BCS bowl bids as at-large teams due to their ranking and their season records.
2015 ORANGE BOWL: No. 1 Clemson vs. No. 4 Oklahoma
In the playoff system, the Orange Bowl functions as a semifinal game this season.

BCS SUGAR BOWL: No. 8 Notre Dame vs. No. 9 Florida State
Because Notre Dame is ranked within the top eight, the Fighting Irish receive a BCS bowl berth. While Ohio State is ranked higher and has a better record than Florida State, no more than two teams from any conference can be represented in BCS bowls unless the BCS Championship Game features teams from the same conference.
2015 SUGAR BOWL: No. 12 Ole Miss vs. No. 16 Oklahoma State
