It's pretty simple actually. Ohio State proved themselves when they whipped Bama'a *** and then Oregon for the Championship last year. They return nearly everybody from that team whereas teams like Bama, Oregon, and Florida State lost most of their best players from last year.
LSU was a 5 loss team last year. LSU hasn't proved anything other than Fournette is really good. They only good team they played, Miss State, gave them a hard time. Their QB has fewer than 10 completions in 3 of 5 games. He was 4 of 14 passing vs Eastern Michigan.
So, yes, i have no idea how good LSU is and neither does anybody else if they are honest. We will find out more this weekend against Florida.
You also missed the part where i said i don't know what to expect of the Michigan vs Mich State game for pretty much the same reason as LSU. Unlike Ohio State, MSU is not the same team as last year. They are significantly different and i'm not sold on Conner Cook as a great QB.
Seem to me that i am applying the same standards to Big Ten teams as SEC teams. In other words, i wait to see things on the field and i don't just buy hype.
