Maybe you should learn some old fashioned reading comprehension. This is about who deserves to be ranked where, in the final four.
Even though Clemson may very well win it all again, there's no doubt that both LSU and Ohio St deserve to be ranked above Clemson at this point. The difference in those three teams is fairly slim, at least as it appears, HOWEVER, because of the schedules of both LSU and OS, they earned that rankings much more than Clemson would have.
Clemson was very fortunate last year to draw the ND matchup even though most everybody agreed that Oklahoma was the better team.
Furthermore, Clemson is in a position to rest their starters more often during the year because of their lackluster schedule. By theory, they are better rested and probably healthier when the playoffs come. There is no disputing the quality of their schedule compared to the two teams ranked ahead of them in the playoffs. There's no doubt they have a distinct advantage over the SEC and Big 10 when it comes to schedules and the quality of those schedules.
This will end up being the driving force behind Dabo leaving Clemson and taking the Bama job when it opens. He will want to prove that he is good enough to navigate his team through a tougher conference schedule and then winning the final four matchups. If you don't think so, just go look at his reactions when his schedule is brought up as a huge advantage for his team.
