If my only criteria is strength of schedule, yes, LSU deserves the #1 spot right now. But that's not how I rank teams. I try to rank based upon all factors together, as best I can.
So:
1. Ohio State
2. Alabama
3. LSU
4. Oklahoma
5. Clemson
6. Wisconsin
Explanation: Ohio State looks like the most complete team in the country to me. A very good offense and what appears to be an elite level defense. Their SOS isn't great, so this ranking will either be confirmed or denied in a few weeks. Alabama has the best offense in the country, IMO, with at least a top 30 level defense. Not great, but more than enough when paired with Tua and company. You could convince me LSU deserves to be higher based upon SOS, but I do not think their defense is very close to ours and I believe our offense is better. That said, they are solidly among the contenders to win it all. They'll face us head to head, so if my ranking is incorrect, it will be proven on the field in a few weeks. I've got Oklahoma above Clemson because I do not believe last year's results should govern this year's rankings this deep into the season. I think OU's defense is improved enough that they would beat Clemson head to head right now. But I admit, Jalen looked more human (relative to the first 5 games) against what I think is only an average defense in Texas. Finally, I think Clemson would beat Wisconsin today and I'm not ready to move Penn State into the top 6.
This is all going to work itself out, at least with head to head match ups. Ohio State is going to face Wisconsin (and Penn State and Michigan). Alabama and LSU are going to play, and the shame of it all is that one team is going to be eliminated from every possible championship in all likelihood. Oklahoma and Clemson have much clearer paths. I'm pulling for Clemson to wet the bed because I don't think they'll deserve the spot they get when its all said and done. Say LSU loses to us by 1. We go 13-0. Does that LSU team, at 11-1 playing the schedule they will have played, deserve to be left out in favor of a Clemson team whose best wins are going to be over a 7-5 Texas A&M or a 7-5 South Carolina? No, but they'll get it left out anyway.
