The BCS ranking system was implemented in 1998 in order to facilitate the determination of a national champion in NCAA Division I-A football while helping preserve its century old bowl system. Although modifications have been made to the BCS ranking system since its creation, most importantly the weight human polls contribute to the rankings, there is still debate as to whether or not this system is legitimate.
The sheer number of football teams that currently play at the collegiate level of Division 1-A, makes the task of determining a single team the true "national champion" each year daunting by itself. The BCS promotes its current system as the best alternative to a true playoff series amongst the top-ranked teams nationally each year. This argument stands true for the time being, as a playoff system amongst all of the BCS conferences would be quite time consuming and complicated. The BCS was originally established by the six most powerful conferences at the time, but has since allowed others (at least four) to participate to some degree in their shot at the national title each year.
Since the creation of the BCS, the system has generated controversy nearly every year as at least one team that has gone undefeated during regular season play has been denied a chance to be crowned the "national champion" of that season's play. Because the system takes into account to some degree the overall strength of schedule, the BCS defends this as a reasonable and plausible explanation. Even though the BCS has some backing to the explanation of its rankings, the topic of finishing a season undefeated and not being allowed a chance to play in the championship game has been the topic of much debate.
The BCS ranking system, in an overall sense, claims itself to provide an overall sensation of playoff games throughout the entire regular season of college football play. Based on the prior argument concerning the fact that many undefeated teams who are members of the BCS have been denied a chance to play in the championship match-up, this topic is debatable. Although official BCS rankings are not released until after inter-conference play takes place each season, the AP and Coach's Poll, which account for two-thirds of the BCS rankings, are established during and even before the BCS rankings are officially released, teams are subject to judgment prior to entering the BCS ranking arena. Because of the fact that a systematic ranking by computer analysis accounts for the remaining third of the vote in the rankings, there are some questions that arise as to whether or not the BCS ranking system is rational.
Collegiate athletes are not allowed to be paid for their performance on the field, but a great majority of them have aspirations to advance to a professional-level at which they will be paid post college. Based on the current BCS ranking scenario, a loss later in the season has much more potential to negatively effect a team's overall standing at the end of regular-season play. Because of this effect, it becomes increasingly important for teams in race for playing in the national championship game to continue winning the entire season even if they have clearly established themselves as an undisputed candidate based on prior performance. The fact that losses later in the season have a more profound impact on a team's overall final standings, often requires that teams continue to play their top-performing athletes despite injuries in order to maintain their ranking. If a playoff system were to be implemented, the chances of injured athletes having the opportunity to restore their health to a higher level would be increased if one loss late in the season would not ruin their entire hopes of playing in the championship game. This point seems to be reasonable from both the players' and spectators' points of view, as both would like to maximize and preserve their positive gains provided via football.
The debate surrounding whether or not the BCS is legit or just BS is something college football fans will have to endure until something else is implemented for determining the national champion for the time being. The arguments both for and against the BCS seem to make a lot of sense and endless depending on who you're talking to. For now, the iron remains hot, and moldable... What changes we will see in the future remains unclear for now though.
