Haha, like I said, you're probably right, BUT...
...it's not like LSU doesn't have issues of it's own that is has been struggling to fix over the past couple years -- and those issues will most likely be amplified simply because it's their very first game of the season with some new coaches and a new offensive system.
Firing your coach mid-season is usually a significant factor and this usually leaves lasting ripples of instability into the following season.
You're also probably right about most of their starters -- however, a big exception is at the QB position, and that's not all that insignificant.
