As of right now the only factor that is missing from the BCS formula is the last computer poll, which is due out on the 19th.
When all in, the highest and the lowest computer polls will be thrown out and the middle three averaged to give a single "computer ranking". This ranking is then weighted equally with both the Coach's Poll and the Harris Interactive Poll. The average of the three is a team's score, which is then used to rank the teams -- we know all this.
If today we applied the same procedures to what we have, this is how the top three would be ranked.
BCS Rank Team Avg. Ranking
#1 Oklahoma 2.500
#2 Alabama 2.833
#3 Missouri 3.000
This could change with the last of the computer entries. It appears that we have the most to lose with regards to that last poll. Statistically speaking, even in the best case scenario, we will not increase the final calculation enough to matter. In other words, we only gain if the others drop.
