Niether Clemson or OSU are out of the playoffs due to these early losses. The problem is, getting into the playoffs is no longer in their hands, they need help from other teams to lose to allow one or both of them to climb back into the top 4.
Alabama could very possibly give both Georgia and Texas A&M losses to bump one or both out of the top 4. OU could possibly run the table so that doesn't help OSU and Clemson. Notre Dame looks susceptible to a loss or two this year. Their are numerous possibilities for either (or both?) to get into the playoffs, they just cannot lose again or even have close wins.
