The fourth column going from left to the right tells the game by game win probability according to the S&P rankings. So Syracuse has a 7.2% chance of winning next week according to S&P, and obviously all the games above are just wins. When you look at all the pretty colors in the table, the chart gives the percent probability of how many wins we're going to have on a week to week basis. The bottom row is probably what everyone's here for, and it states we have a 97.8% chance of at least reaching a bowl this year at 6 wins (bottom right hand corner of the percents). It also states our most likely scenario is 8 wins this year at 32.1%, and we have a 0.1% chance of getting to 12-0. Every other team in the Atlantic besides Clemson has a 0.0% chance of getting to 12-0 right now.
What's in parentheses you don't really need to worry about, but it is the change of percentage we had from last week. So for the clemson game, we have a 2.6% better chance than we did according to the rankings last week to beat them.
